https://obrazki.elektroda.pl/3232939000_1584727899_thumb.jpg Witajcie moi drodzy Dzisiaj przedstawię moją recenzję gniazda-ładowarki USB do ściany oferującego 6 portów o wydajności prądowej do 3.5A (a przynajmniej wedle sprzedawcy). W temacie pokażę testy wydajności prądowej, nagrzewania się układu, zajrzę do środka zasilacza, narysuję jego schemat i na koniec przedstawię jak można łatwo go zmodyfikować. Zakup, przesyłka i wypakowanie gniazda Gniazdo zakupiłem 28 stycznia 2020 na eBayu za 4.10£ (na nasze to 20 złotych) w ofercie pod tytułem 2/3/4/6 USB Wall Socket Charger AC/DC Power Adapter Plug Outlet Plate Panel (wybrałem wersję z 6 portami USB): https://obrazki.elektroda.pl/7793493400_1584739683_thumb.jpg W tym momencie ceny tego typu gniazd są nieco większe, ale dalej są one dostępne w sieci od różnych sprzedawców i w różnych konfiguracjach (2, 3, 4, 6 portów): https://obrazki.elektroda.pl/7916650400_1584739801_thumb.jpg https://obrazki.elektroda.pl/9258522900_1584739854_thumb.jpg https://obrazki.elektroda.pl/4304333800_1584739869_thumb.jpg Paczka przyszła około 8 marca - standardowo listonosz po prostu wsadził ją do skrzynki na listy, nie dał do rąk własnych (czyli brak potwierdzenia odbioru): https://obrazki.elektroda.pl/5676354800_1584739976_thumb.jpg https://obrazki.elektroda.pl/3753687400_1584739986_thumb.jpg Gniazdo prezentuje się tak jak na zdjęciach z aukcji. W paczce było dodatkowo w foliowym opakowaniu, które było podpisane 'Safety electrician intelligent home'. Można by tu mieć nadzieję, że Chińczycy po prostu się pomylili i dali folię z innego produktu - ale nic bardziej mylnego, oni z reguły reklamują swoje produkty tego typu sloganami. Z tyłu folii widoczne są parametry: USB B220V 5V oraz chyba numery/identyfikatory serii, np. HR-SH-3C-085-D ale żaden nie daje sensownych wyników w Google. Na opakowaniu też w jakimś celu umieszczony jest schemat podłączania przełączników do żarówek: https://obrazki.elektroda.pl/8570119300_1584740218_thumb.jpg Celowości tego trudno jest się doszukać. Na pewno plusem jest to, że w zestawie są śruby do mocowania: https://obrazki.elektroda.pl/6847468900_1584740281_thumb.jpg https://obrazki.elektroda.pl/4576986800_1584740283_thumb.jpg Z tyłu gniazda mamy konkrety, jego parametry to: 110V-250V 5V 1000mA-3500mA Dodatkowo podpisane są styki od przewodu sieciowego, jedynie linie N i L, bez uziemienia. Zaraz je podłączymy i dokładnie przetestujemy. Pierwszy test gniazda - wydajność prądowa i napięcie Pierwszy test gniazda wykonałem za pomocą słynnego narzędzia USB Doctor (które mam już sprawdzone i wiem, że daje w miarę rzetelne wyniki): https://obrazki.elektroda.pl/7737509700_1583423133_thumb.jpg oraz za pomocą sztucznego obciążenia USB o nazwie LD25: https://obrazki.elektroda.pl/9464077100_1583440387_thumb.jpg LD25 opisywałem tutaj: https://www.elektroda.pl/rtvforum/viewtopic.php?p=18513078#18513078 LD25 pozwala ustawić prąd obciążenia (od 0 do 4A), pokazuje napięcie i moc wyjścia, z kolei USB Doctor dodatkowo pokazuje napięcie (tylko w celu weryfikacji). Podłączyłem całość do gniazda i sprawdziłem kolejno napięcie dla różnych wartości prądu. (Wszystkie porty USB są w gnieździe spięte razem, więc mogłem dokonać pomiaru tak jak dokonałem) Na początek - brak obciążenia: https://obrazki.elektroda.pl/8556641000_1584740855_thumb.jpg Następnie obciążenie 0.1A: https://obrazki.elektroda.pl/5977577400_1584740604_thumb.jpg Następnie obciążenie 0.25A: https://obrazki.elektroda.pl/2506688100_1584740640_thumb.jpg Następnie obciążenie 0.5A: https://obrazki.elektroda.pl/6906953000_1584740730_thumb.jpg Następnie obciążenie 0.75A: https://obrazki.elektroda.pl/6906953000_1584740730_thumb.jpg Następnie obciążenie 1.00A: https://obrazki.elektroda.pl/7416659900_1584741046_thumb.jpg Następnie obciążenie 1.50A: https://obrazki.elektroda.pl/9369317300_1584741064_thumb.jpg Następnie obciążenie 2.00A: https://obrazki.elektroda.pl/1116344700_1584741092_thumb.jpg Następnie obciążenie 2.50A: https://obrazki.elektroda.pl/1529512100_1584741117_thumb.jpg Następnie obciążenie 2.75A (tu zaczyna się spadek napięcia): https://obrazki.elektroda.pl/1685693100_1584741189_thumb.jpg Następnie obciążenie 3.00A: https://obrazki.elektroda.pl/4045580700_1584741436_thumb.jpg Następnie obciążenie 3.25A: https://obrazki.elektroda.pl/8008008300_1584741473_thumb.jpg Następnie obciążenie 3.5A (wg. obudowy tyle ta ładowarka jest w stanie zapewnić): https://obrazki.elektroda.pl/3970760500_1584741517_thumb.jpg Następnie obciążenie 3.75A: https://obrazki.elektroda.pl/2541363200_1584741575_thumb.jpg Następnie obciążenie 4.00A: https://obrazki.elektroda.pl/4188070500_1584741616_thumb.jpg Zmierzone napięcie za pomocą USB Doctora i LD25 (ono też pokazuje napięcie) zawsze było podobne i błąd był rzędu dziesiątych ampera. Wyniki ze wszystkich pomiarów powyżej przedstawiłem w tabelce: Obciążenie Napięcie05.40.15.40.255.40.55.415.41.55.425.42.55.42.755.234.83.254.43.54.13.753.943.7 Tutaj rzuca się w oczy przede wszystkim jeden problem - napięcie na wyjściu ten ładowarki jest nieco za wysokie. Zgodnie ze standardem USB 2.0 napięcie to powinno być od 4.4V do 5.25V, więc te 5.4V na wyjściu ładowarki to troszkę za wysoko. A tam zdecydowanie jest 5.4V, sprawdziłem to trzema miernikami (USB Doctor, LD25 oraz UT10A). Z kolei sama wydajność prądowa jest dość dobra, chociaż nieco przed obiecanym 3.5A już napięcie spada, mogłoby być troszkę lepiej. Teardown, czyli zaglądamy do środka Nadszedł czas zdjąć obudowę i przyjrzeć się dokładnie co jest w środku. Przednia pokrywa znajduje się na samych zaczepach: https://obrazki.elektroda.pl/1643549200_1584742026_thumb.jpg https://obrazki.elektroda.pl/1287824500_1584742025_thumb.jpg Widoczna wtedy jest w środku jedna płytka z małym zasilaczem impulsowym: https://obrazki.elektroda.pl/1881223400_1584742118_thumb.jpg https://obrazki.elektroda.pl/7574963500_1584742117_thumb.jpg Aby ją wyjąć, należy wykręcić śrubki trzymające przewody sieciowe: https://obrazki.elektroda.pl/4522677200_1584742083_thumb.jpg Tak prezentuje się ona po wyjęciu. Transformatorek jest po jednej stronie, a reszta po drugiej: https://obrazki.elektroda.pl/9307427200_1584742152_thumb.jpg https://obrazki.elektroda.pl/6059579800_1584742152_thumb.jpg Na płytce widać datę 2019-03-07, możliwe, że to data produkcji. Jeśli tak to gniazdko trafiła do mnie akurat jakiś rok po wyprodukowaniu. https://obrazki.elektroda.pl/5738923000_1584742390_thumb.jpg https://obrazki.elektroda.pl/7473492100_1584742212_thumb.jpg Teraz prześledzimy cały układ po kolei, element po elemencie. W celu lepszej widoczności elementów usunąłem z płytki większość gniazd USB i część zdjęć poniżej będzie już bez tych gniazd. Zaczynamy: Na wejściu, na linii L, widzimy bezpiecznik T3.15A 250V. Czemu jest on na taki duży prąd? Nie mam pojęcia. https://obrazki.elektroda.pl/1068783000_1584742493_thumb.jpg Dalej znajdują się cztery diody tworzące mostek Greatza, każda podpisana M7, czyli zwykłe 1N4007 w SMD: https://obrazki.elektroda.pl/2302499600_1584742647_thumb.jpg Każda dioda 1N4007 jest w obudowie DO-214AC: https://obrazki.elektroda.pl/1671954000_1584875205_thumb.jpg Te oznaczenie M7 można oczywiście też odczytać z noty katalogowej: https://obrazki.elektroda.pl/6227884800_1584875256_thumb.jpg Sam duży kondensator elektrolityczny, znajduje się oczywiście tuż za mostkiem Greatza, jest na napięcie 400V i ma pojemność 15uF: https://obrazki.elektroda.pl/2248192100_1584742701_thumb.jpg Dalej jest już podłączony główny kontroler przetwornicy, U1, oraz MOSFET którym on steruje: https://obrazki.elektroda.pl/3498321300_1584742917_thumb.jpg https://obrazki.elektroda.pl/8890232700_1584743337_thumb.jpg Ten kontroler U1 to DP2281. https://obrazki.elektroda.pl/5843729600_1584743007_thumb.jpg https://obrazki.elektroda.pl/6021114100_1584743025_thumb.jpg Dokładny opis wyprowadzeń DP2281 pokazuję poniżej: https://obrazki.elektroda.pl/4393650000_1584965179_thumb.jpg Cała nota tutaj: 1017454 W jego nocie katalogowej można wyczytać też m. in. częstotliwość jego pracy: https://obrazki.elektroda.pl/3744106000_1584743056_thumb.jpg Również można wyczytać informacje, że ta przetwornica jest w topologii flyback - ale to można też wywnioskować też z innych rzeczy. W tej nocie katalogowej jest też schemat przykładowej przetwornicy na tym scalaku: https://obrazki.elektroda.pl/2316927600_1584743614_thumb.jpg Sam DP2281 zasilany jest poprzez elementy pokazane poniżej: https://obrazki.elektroda.pl/3072078300_1585262166_thumb.jpg Na zasilanie DP2281 składa się kondensator elektrolityczny na 50V, rezystor przez którego jest on ładowany z sieci oraz diodę prostowniczą przez którą jest on ładowany z uzwojenia feedback transformatora (gdy przetwornica wystartuje). Obok DP2281 jest MOSFET podpisany MKX 1905, nie zidentyfikowałem go, ale nie jest to aż takie istotne. https://obrazki.elektroda.pl/2810196700_1584742960_thumb.jpg Układ z diodą, kondensatorem i rezystorem obok pełni funkcję snubbera - gasi szpilki napięcia na uzwojeniu pierwotnym transformatora: https://obrazki.elektroda.pl/8496663800_1584743222_thumb.jpg Prostowanie prądu po stronie wtórnej jest zrealizowane za pomocą dwóch układów CLR6219 połączonych równolegle: https://obrazki.elektroda.pl/1938570000_1584743541_thumb.jpg Notę katalogową CLR6219 można znaleźć w sieci, niestety jednak nie po angielsku: https://obrazki.elektroda.pl/5705614100_1584743727_thumb.jpg Znajduje się w niej rozpiska pinów tego układu: https://obrazki.elektroda.pl/9385721100_1584743754_thumb.jpg Jak również opisane są sposoby jego zastosowania: https://obrazki.elektroda.pl/2254533600_1584743959_thumb.jpg Tuż za CLR6219 podłączone są dwa kondensatory elektrolityczne na napięcie 10V i o pojemności 680uF: https://obrazki.elektroda.pl/1787391200_1584744520_thumb.jpg https://obrazki.elektroda.pl/6588103400_1584744520_thumb.jpg Kondensatory te są podpisane CD288H, w sieci można znaleźć ich notę katalogową i niektóre parametry: https://obrazki.elektroda.pl/7881596900_1585587159_thumb.jpg Pełna nota tutaj: 1017451 Po stronie wtórnej układu znajdują się elementy odpowiedzialne za regulację napięcia - TL431, który za pomocą dzielnika rezystorowego ustala napięcie wyjścia oraz transoptor PC817C, który łączy stronę wtórną z pierwotną i zapewnia między nimi izolację galwaniczną: https://obrazki.elektroda.pl/6877493900_1584743312_thumb.jpg TL431 to programowalne źródło napięcia referencyjnego, można powiedzieć, że działa tak jak dioda Zenera której sami ustalamy napięcie. https://obrazki.elektroda.pl/9272569800_1584875643_thumb.jpg W tym zasilaczu występuje w obudowie SOT-23: https://obrazki.elektroda.pl/6497083700_1584875509_thumb.jpg Pełną notę katalogową TL431 umieszczam tutaj: 1017452 PC817C to transoptor, bierze on udział w pętli sprzężenia zwrotnego i regulacji napięcia przetwornicy: https://obrazki.elektroda.pl/2224880200_1584965314_thumb.jpg Podłączony jest do pinu Feedback (FB) (pin numer 2) DP2281 i w zależności od napięcia na nim zmienia PWM przetwornicy (wraz z pinem numer 4 - CS, czyli Current Sense Input) Pełną notę katalogową PC817C umieszczam tutaj: 1017450 Schemat zasilacza Po rozłożeniu zasilacza poświęciłem troszkę czasu i narysowałem dla Was jego schemat w Eagle. Całość bazowałem na dokładnych oględzinach płytki oraz na notach katalogowych elementów: https://obrazki.elektroda.pl/3214017900_1585071229_thumb.jpg Wartości i nazwy części na schemacie są w miarę możliwości przepisane 1:1 z elementów i oznaczeń na PCB. Stąd na schemacie są osobno oznaczenia w stylu "EC1" co oznacza kondensator elektrolityczny, i "C1" co oznacza zwykły kondensator. Wartości elementów oczywiście trzeba umieć odczytać, np. 222 przy kondensatorze od snubbera oznacza tak naprawdę 2.2nF, w razie czego polecam stronę: https://circuitdigest.com/calculators/capacitor-value-code-calculator Nie daję 100% pewności, że schemat jest poprawny, ale można go pobrać tutaj w formacie Eagle (plik .sch): 1017453 Przyjrzymy się teraz poszczególnym fragmentom schematu: https://obrazki.elektroda.pl/4311311600_1585071402_thumb.jpg Dla wygody podzieliłem go na osobne sekcje. Napiszę o nich teraz kilka słów. Ogólnie cała przetwornica jest w topologii flyback a regulacja napięcia odbywa się poprzez sprzężenie zwrotne ze strony wtórnej. Sekcja 1 jest podłączona bezpośrednio do sieci, znajduje się tam bezpiecznik, mostek Greatza który prostuje napięcie sieciowe oraz kondensator elektrolityczny który potem ładuje się prawie do wartości szczytowej napięcia z sieci (z 230V AC robi się około 325V DC). Sekcja 2 to zasilanie kontrolera przetwornicy DP2281. Kondensator 50V 10uF stale ładowany jest przez rezystor R12 o rezystancji 2MΩ, ale sam prąd płynący przez ten rezystor nie starcza do działania przetwornicy, starcza tylko by ona mogła wystartować. Od momentu gdy przetwornica wystartuje kondensator 50V 10uF ładowany jest też z uzwojenia feedback poprzez diodę prostowniczą, dzięki czemu zasilacz może dalej pracować. Sekcja 3 to jest snubber, on gasi tzw. "szpilki", czyli szpilkowe przepięcia które pojawiają się na skutek indukcyjności rozproszenia transformatora. W teorii układ bez niego by może działał, ale MOSFET byłby narażony na większe grzanie się i też również na uszkodzenia. Sekcja 4 to trzy rezystory o bardzo małym oporze podłączone poprzez kolejny rezystor do pinu CS, czyli Current Sense od kontrolera przetwornicy. Ten pin realizuje pomiar prądu przepływającego przez uzwojenie pierwotne i MOSFET. Przetwornica na bazie sygnału z tego pinu (oraz sygnału z pinu FB - Feedback) ustawia odpowiednio wypełnienie sygnału kluczującego tranzystor by utrzymać odpowiednie napięcie na wyjściu. Sekcja 5 podłączona jest do uzwojenia wtórnego, dwa układy CLR6219 są po prostu tu w roli szybkiej diody która prostuje impulsy prądu o częstotliwości pracy przetwornicy i pozwala uzyskać z nich prąd stały i nim ładuje kondensatory. Sekcja 6 to minimalne obciążenie dla przetwornicy, wiele przetwornic nie powinno być uruchamianych kompletnie bez obciążenia, dlatego tu te rezystory znajdują się na PCB. Sekcja 7 to zasadniczo tylko programowalne napięcie odniesienia TL431 wraz z potrzebnymi do jego działania elementami. Ustala ono napięcie wyjścia, modyfikacja odpowiednich rezystorów pozwala nam tu zmienić napięcie wyjścia (ale tylko w pewnym małym stopniu). Sygnał z TL431 idzie do transoptora PC817 (zapewniającego separację galwaniczną) a dalej trafia do pinu FB (Feedback) od kontrolera przetwornicy, który wraz z pinem CS (Current Sense) ustawia odpowiednio PWM pracy DP2881 by utrzymać odpowiednie napięcie na wyjściu. Sekcja 8 to główny MOSFET/klucz przetwornicy wraz z rezystorem bramkowym podłączonym do pinu GATE sterownika DP2881. To ten MOSFET z odpowiednią częstotliwością przepuszcza prąd o napięciu około 300V poprzez uzwojenie pierwotne transformatora. Na schemacie zostawiłem poza sekcjami: - DP2281, główny kontroler przetwornicy z całym mechanizmem doboru częstotliwości pracy na bazie wejścia pinów CS/FB - kondensator CY1, który łączy stronę wtórną z pierwotną i w dużym uproszczeniu jego rolą jest redukcja zakłóceń. Prosta modyfikacja napięcia wyjściowego zasilacza Napięcie wyjściowe zasilaczy zrealizowanych tak jak ten można względnie łatwo modyfikować, a przynajmniej w pewnym zakresie. Każda większa zmiana napięcia wyjściowego wymagałaby ponownego przemyślenia/przeprojektowania wartości elementów, w tym ilości zwojów na uzwojeniu pierwotnym, ale małą zmianę napięcia można zrealizować w pełni poprzez modyfikacje dzielnika napięcia przy TL431. W tym celu postanowiłem wylutować element R3, rezystor o kodzie 3301, czyli o rezystancji 3.3kΩ: https://obrazki.elektroda.pl/9813562700_1585000078_thumb.jpg Po wylutowaniu zweryfikowałem jego rezystancje: https://obrazki.elektroda.pl/3957022800_1584745805_thumb.jpg Bez tego rezystora płytka prezentowała się tak: https://obrazki.elektroda.pl/7118086500_1584745831_thumb.jpg Następnie wziąłem rezystor o nieco większym oporze, 3.9k: https://obrazki.elektroda.pl/1221514300_1584745862_thumb.jpg I wlutowałem go na jego miejsce: https://obrazki.elektroda.pl/3789875200_1584745891_thumb.jpg Następnie wykonałem ponownie testy zasilacza przy różnych prądach: https://obrazki.elektroda.pl/1663456100_1584746125_thumb.jpg https://obrazki.elektroda.pl/1807575500_1584746126_thumb.jpg https://obrazki.elektroda.pl/1445407300_1584746149_thumb.jpg https://obrazki.elektroda.pl/1921538800_1584746149_thumb.jpg https://obrazki.elektroda.pl/4556257600_1584746170_thumb.jpg https://obrazki.elektroda.pl/2882453000_1584746171_thumb.jpg https://obrazki.elektroda.pl/8405067000_1584746226_thumb.jpg https://obrazki.elektroda.pl/6892066500_1584746225_thumb.jpg Po podmianie rezystora napięcie na wyjściu wynosi 4.9V i utrzymuje się takie aż do obciążenia 2.5A, a potem przy 3.0A obciążenia spada do 4.7V. Czyli zasilacz zachowuje się analogicznie do tego co było przed modyfikacją, lecz napięcie nie przekracza już tego ze standardu USB - czyli modyfikacja się powiodła. Mini-regulacja napięcia za pomocą potencjometru W ramach małej demonstracji postanowiłem jeszcze spróbować wlutować potencjometr na miejsce tego rezystora. Taka modyfikacja pozwoli w małym stopniu nam samodzielnie regulować napięcie na wyjściu przetwornicy. Wybrałem trymmer 2.7k i rezystor 2.2k: https://obrazki.elektroda.pl/4724045600_1585000492_thumb.jpg https://obrazki.elektroda.pl/4372602600_1585000503_thumb.jpg W ten sposób rezystor 3.3k zastąpiłem regulacją rezystancji od 2.7k do 6k: https://obrazki.elektroda.pl/1450418500_1585000828_thumb.jpg Po tej modyfikacji wykonałem testy regulacji napięcia przy obciążeniu 2A: https://obrazki.elektroda.pl/4765967900_1585001226_thumb.jpg https://obrazki.elektroda.pl/8845651800_1585001234_thumb.jpg https://obrazki.elektroda.pl/5337369800_1585001241_thumb.jpg Wygląda na to, że wszystko jest ok. Można by tu jeszcze dokładnie od nowa pomierzyć napięcia dla danego prądu w obu ustawieniach potencjometru, ale uznałem, że cała modyfikacja była tylko w celu pokazania, że tak się da, więc dokładniejsze pomiary są zbędne. Końcowa modyfikacja napięcia wyjścia zasilacza Ostatecznie zrezygnowałem z regulacji napięcia i na miejsce rezystora R3 3.3k postanowiłem dać wartość 3.9k, rezystor w obudowie SMD: https://obrazki.elektroda.pl/8631133700_1584875014_thumb.jpg Płytka po wlutowaniu rezystora: https://obrazki.elektroda.pl/9584265400_1584875059_thumb.jpg Po tej modyfikacji zasilacz daje stabilne 4.9V zamiast 5.4V/5.5V i w takiej wersji ja go preferuję, chociaż myślę, że te 5.4V też jest jeszcze w ostateczności dopuszczalne. Siedmiogodzinny test grzania się zasilacza pod obciążeniem 3A Test wykonałem tylko by z grubsza określić czy zasilacz w ogóle sprawdza się pod takim obciążeniem i by przekonać się jakie elementy i jak bardzo będą się grzały. Test wykonałem w temperaturze otoczenia 19°C. Test wykonałem bez obudowy i poza ścianą, więc oczywiście należy pamiętać że pewnie zasilacz wbudowany w ścianę grzałby się mocniej. Początek testu (godzina 18:45): https://obrazki.elektroda.pl/9776209700_1584874516_thumb.jpg Koniec testu (godzina 1:45): https://obrazki.elektroda.pl/4382518000_1585145366_thumb.jpg https://obrazki.elektroda.pl/8536410200_1584874738_thumb.jpg https://obrazki.elektroda.pl/6746980900_1584874753_thumb.jpg Największą temperaturę zanotowałem po stronie wtórnej, na układach CLR6219. Jeden z nich grzał się nieco mocniej. Bardzo duża temperatura była też na kondensatorach elektrolitycznych na wyjściu przetwornicy, a to nie jest dobry znak, gdyż możliwe, że z czasem uległyby one wyschnięciu i degradacji. Oprócz tego dość ciepła była też reszta elementów, ale już nie tak bardzo jak pozostałe. Test działania zasilacza na różnych napięciach wejściowych (różne napięcia sieciowe) Z ciekawości sprawdziłem jak ładowarka radzi sobie na różnych napięciach zasilania, od 20V AC do 250V AC. Użyłem do tego autotransformatora TDGC2J-2: https://obrazki.elektroda.pl/1723214700_1584901200_thumb.jpg Jego napięcie wejścia to 220V, a wyjście można ustawić od 0V do 250V.

Czyli gniazda zarówno można użyć gdy mamy sieć 230V jak i dla 120V (np. w USA). Przy napięciu 60V AC zaczynają się problemy i jest już 4.6V DC na wyjściu zamiast 4.9V. Przy 50V AC jest już 4.4V DC co o dziwo jeszcze wciąż zalicza się do standardu USB. Przy 40V AC jest już jakieś 4V DC na wyjściu, to już troszkę za mało. Przy około 30V AC zasilacz już gaśnie, włącza się tzw. 'Undervoltage protection'UVLO, którą oferuje DP2281. Test zwarcia na wyjściu zasilacza Testowany zasilacz jest w topologii flyback, więc powinien być odporny na zwarcia na wyjściu, a do tego to samo można wyczytać z noty katalogowej kontrolera tej przetwornicy (DP2281), ale i tak postanowiłem to sprawdzić. Przygotowałem sobie dwie zworki do robienia zwarcia w bezpieczny sposób oraz dodatkowo do drugiego portu podłączyłem USB Doctor i małą lampkę LED na USB by widzieć co się dzieje: https://obrazki.elektroda.pl/2334630100_1584992898_thumb.jpg Filmik przedstawia jak układ się zachowuje w momencie zwarcia: https://filmy.elektroda.pl/10_1584997607.mp4 Jak widać, zasilacz jest odporny na zwarcia. Modyfikacja ograniczenia prądu - zwiększamy wydajność prądową zasilacza Nieco wcześniej zademonstrowałem jak można wprowadzić drobną modyfikację w układzie napięcia odniesienia (z którego sygnał idzie na pin FB układu DP2281) w celu skorygowania napięcia na wyjściu przetwornicy. Teraz pokażę, jak można zwiększyć wydajność prądową układu poprzez modyfikację oporu bocznika przy pinie CS (Current Sense) od układu DP2281. Postaram się w ten sposób powalczyć ze spadkiem napięcia który następuje gdy obciążymy zasilacz prądem rzędu 3A. Na początek ostrzeżenie - nie ma nic za darmo. To nie jest tak, że możemy sobie do woli zmniejszać tu rezystancję. Wydajność prądową przetwornicy ogranicza bardzo wiele czynników, grzanie się elementów, transformator, dioda prostownicza po stronie wtórnej, itp. Modyfikacja którą proponuje będzie polegać na zmianie rezystancji między pinem CS (Current Sense kontrolera przetwornicy) a masą, tutaj: https://obrazki.elektroda.pl/1139062600_1585071500_thumb.jpg Na PCB to miejsce wygląda tak: https://obrazki.elektroda.pl/7053661300_1584998689_thumb.jpg I już z samego zdjęcia rzuca się w oczy to, że jest tam miejsce na jeszcze jeden rezystor. Czyżby producent początkowo zamierzał pozwolić na większe prądy, a potem uznał, że np. nie warto, by inne komponenty za bardzo się grzeją? Może po prostu zmienił inne komponenty na słabsze i tańsze odpowiedniki? W tym miejscu są trzy rezystory 2R70 połączone równolegle. Można łatwo policzyć (samodzielnie lub za pomocą kalkulatora online) ich rezystancję zastępczą: https://obrazki.elektroda.pl/3434660800_1584998801_thumb.jpg Obrazek powyżej pochodzi z kalkulatora stąd: https://www.allaboutcircuits.com/tools/parallel-resistance-calculator/ Spróbujemy zmienić tę rezystancję na mniejszą - po prostu poprzez dolutowanie tam kolejnego rezystora. Ale to zaraz. Modyfikacja ograniczenia prądu - pomiary przed modyfikacją Skoro już wiemy co zamierzamy zmodyfikować, to potrzebujemy mieć jakiś punkt odniesienia. W tym celu zmierzymy dokładnie jak zachowuje się przetwornica jeszcze bez modyfikacji przy prądzie obciążenia od 2.80A do 4.00A i zapiszemy wyniki do tabelki. Oto wyniki: Napięcie na wyjściu a prąd obciążenia - wersja bez modyfikacji (rezystancja do masy na pinie CS 0.9Ω): Obciążenie Napięcie 2.84.92.904.83.004.7 3.104.6 3.204.4 3.304.3 3.404.1 3.504.0 3.603.9 3.703.9 3.803.8 4.003.8 Możemy tu zaobserwować, że spadek napięcia zaczyna się od prądu obciążenia 2.9A. Napięcie spada aż do 3.8V przy obciążeniu 4A. Czy uda nam się to polepszyć? Modyfikacja ograniczenia prądu - wykonanie modyfikacji Zgodnie z wcześniejszym planem dobrałem odpowiednio czwarty rezystor do dolutowania w wolno miejsce. Zdecydowałem się na 5.6Ω, gdyż takie połączenie da nam rezystancję zastępczą 0.78Ω: https://obrazki.elektroda.pl/9550570400_1584999073_thumb.jpg Po prostu taki rezystor miałem pod ręką i uznałem, że sprawdzę jak z nim zachowa się przetwornica: https://obrazki.elektroda.pl/8491893500_1584999146_thumb.jpg Nie był potrzebny rezystor aż takiej dużej mocy, po prostu taki miałem dostępny. Po wlutowaniu: https://obrazki.elektroda.pl/8004415400_1584999228_thumb.jpg Następnie od nowa wykonałem pomiary i sprawdziłem spadek napięcia, ale o tym już w następnym akapicie. Modyfikacja ograniczenia prądu - pomiary po modyfikacji Po dolutowaniu rezystora 5.6Ω rezystancja do masy na pinie CS zmieniła się z 0.9Ω na 0.79Ω. Wykonałem od nowa wszystkie pomiary. Wersja z rezystancja 0.79Ω na CS do masy - obciążenie 2.8A: https://obrazki.elektroda.pl/3721546800_1585336983_thumb.jpg https://obrazki.elektroda.pl/3599980500_1585336982_thumb.jpg Wersja z rezystancja 0.79Ω na CS do masy - obciążenie 2.9A: https://obrazki.elektroda.pl/2294579300_1585337061_thumb.jpg https://obrazki.elektroda.pl/3102542300_1585337062_thumb.jpg Część zdjęć pominięta.

Zasilacz od obciążenia 0A aż do 3.7A trzyma napięcie wyjścia 4.9V. To znacznie lepiej, prawie o jeden amper więcej niż było przed zmianami. Więcej nie jestem w stanie sprawdzić gdyż moje LD25 pozwala ustawić obciążenie do 4.09A (wg. manuala do 4A). Teraz trzeba jeszcze sprawdzić jak bardzo grzeje się cały układ przy obciążeniu 4A - ale to już w następnym akapicie. Modyfikacja ograniczenia prądu - nowa dioda prostownicza Po modyfikacji ograniczenia prądu ustawiłem obciążenie na 4A i zostawiłem zasilacz na kilka chwil. Po paru minutach wykonałem kilka pomiarów temperatury pirometrem, i zauważyłem, że układy prostujące napięcie osiągają 70°C: https://obrazki.elektroda.pl/5631455000_1585002489_thumb.jpg Po 10 minutach te układy osiągnęły już temperaturę 95°C: https://obrazki.elektroda.pl/5831751600_1585002524_thumb.jpg To zdecydowanie za dużo! Te diody nie były przygotowane na takie prądy. Uznałem, że zamienię je na jakąś mocniejszą diodę. Najpierw odlutowałem oba CLR2219: https://obrazki.elektroda.pl/2007825400_1585077326_thumb.jpg Wystarczyła tylko duża ilość topnika i zwykła lutownica grotowa by bez problemu dało się oba układy usunąć z płytki: https://obrazki.elektroda.pl/8242103300_1585077383_thumb.jpg Następnie przeszukałem diody z szuflady jakie miałem pod ręką: https://obrazki.elektroda.pl/1735740600_1585077690_thumb.jpg Najlepiej o sprawdziła się dioda Schottkiego VT1045. Wybrałem ją m. in. ze względu na niski spadek napięcia. Na początku sprawdzałem też diody ultraszybkie, ale te co miałem również szybko się grzały. https://obrazki.elektroda.pl/5266912600_1585077542_thumb.jpg Wlutowałem ją na miejsce: https://obrazki.elektroda.pl/5685733600_1585077792_thumb.jpg I wstępnie sprawdziłem czy wszystko działa: https://obrazki.elektroda.pl/1771567600_1585077825_thumb.jpg Działało bez zarzutów, aczkolwiek napięcie na wyjściu nieco spadło, ale o tym dopiero w następnym akapicie. Jeszcze sprawdziłem, o ile zmniejszyło się grzanie - teraz po 10 minut nie było już 95°C, lecz tylko 60°C: https://obrazki.elektroda.pl/5412345600_1585078017_thumb.jpg Ostateczna wersja zasilacza - wersja 4A Zamiana układów CLR2219 na diodę Schottkiego VT1045BP sprawiła, że problem przegrzewania zniknął, ale niestety też nieco znów spadło napięcie przy obciążeniach powyżej 3.6A. Co prawda ta zmiana była tylko o jakieś 0.1-0.5V, ale i tak uznałem, że warto spróbować to skorygować. Postanowiłem po prostu jeszcze zmniejszyć rezystancję na pinie CS, czyli pozwolić przetwornicy na przepływ nieco większych prądów. Wcześniej wlutowałem tam rezystor 5.6Ω, teraz uznałem, że zamienię go na 1.6Ω: https://obrazki.elektroda.pl/3516758100_1585074380_thumb.jpg Zgodnie z obliczeniami powyżej wtedy rezystancja bocznika zmieni się z 0.9Ω na 0.58Ω. Zdjęcie przedstawia już wykonaną modyfikację: https://obrazki.elektroda.pl/7788218000_1585078531_thumb.jpg Po tej zmianie po raz kolejny sprawdziłem napięcie przy różnych obciążeniach. Wyniki okazały się tak dobre, że dam tylko zdjęcie pomiaru przy 4.1A: https://obrazki.elektroda.pl/7567019800_1585079564_thumb.jpg https://obrazki.elektroda.pl/4934375200_1585079567_thumb.jpg https://obrazki.elektroda.pl/7416369900_1585079567_thumb.jpg Po tej modyfikacji zasilacz dla dowolnej wartości prądu obciążenia od 0A aż do 4.1A dawał stabilne 4.9V-4.8V. Przy 4.1A moc na wyjściu sięgała prawie 20W. Żaden z elementów nie grzał się przesadnie a sam zasilacz przeszedł bez problemu sześciogodzinny test pracy. Finalny schemat zasilacza z uwzględnionymi zmianami: https://obrazki.elektroda.pl/8259925900_1585079972_thumb.jpg Zmiany na schemat zostały naniesione w programie Paint, wiec z pewnością się rzuca w oczy co zmodyfikowałem. Podsumowanie Przetestowałem tutaj działanie ładowarki USB-gniazda do ściany z Chin. Produkt okazał się być takiej jakości jakiej się spodziewałem. Nie było wielkiej tragedii, sposób regulacji napięcia nie był aż taki zły, w przetwornicy był obecny gasik (najtańsze ładowarki chińskie nawet go nie posiadają), a nawet był bezpiecznik. Ale mimo to zasilacz nie spełniał raczej ani standardu napięcia USB (było 5.4V), ani nawet nie zapewniał w pełni takiego prądu, jaki był podany na obudowie (zapewniał nieco mniej, potem napięcie spadało). Dlatego też skorzystałem z okazji i również zaprezentowałem tutaj kilka drobnych modyfikacji które tak naprawdę są dość prostymi ale też uniwersalnymi pomysłami i sprawdzą się z wielu innymi przetwornicami, a mianowicie: - modyfikację napięcia wyjścia (i jej regulację w pewnym stopniu) - modyfikację ograniczenia prądu i poprawę niechcianego spadku napięcia przy większym obciążeniu Wszystkie modyfikacje jak najbardziej się powiodły i teraz zasilacz daje radę zapewnić aż do 4A przy stabilnym napięciu 4.8-4.9V! Na koniec chciałbym tylko podkreślić, że oczywiście nie miałem na celu przekonywania kogoś do używania tak zmodyfikowanego zasilacza do ładowania swoich telefonów. To wszystko raczej było pokazane w celach edukacyjnych. Poprzez praktykę można dużo rzeczy zobrazować i zorientować się co i jak działa. Sam rzecz jasna też nie zamierzam podłączać swoich telefonów do tego wynalazku. Pewnie jakby się postarać, to dałoby się nieco więcej jeszcze z tego zasilacza wycisnąć, ale należy pamiętać, że ogranicza nas też sam tranzystor i oczywiście transformator, który jest w stanie przenieść skończoną ilość mocy (a dokładniej ogranicza nas tu maksymalny prąd transformatora powodujący nasycenie się rdzenia).

The TL431 and TL432 devices are three-terminal
adjustable shunt regulators, with specified thermal
stability over applicable automotive, commercial, and
military temperature ranges. The output voltage can
be set to any value between Vref (approximately
2.5 V) and 36 V, with two external resistors. These
devices have a typical output impedance of 0.2 Ω.
Active output circuitry provides a very sharp turn-on
characteristic, making these devices excellent
replacements for Zener diodes in many applications,
such as onboard regulation, adjustable power
supplies, and switching power supplies. The TL432
device has exactly the same functionality and
electrical specifications as the TL431 device, but has
different pinouts for the DBV, DBZ, and PK packages.
Both the TL431 and TL432 devices are offered in
three grades, with initial tolerances (at 25°C) of 0.5%,
1%, and 2%, for the B, A, and standard grade,
respectively. In addition, low output drift versus
temperature ensures good stability over the entire
temperature range.
The TL43xxC devices are characterized for operation
from 0°C to 70°C, the TL43xxI devices are
characterized for operation from –40°C to 85°C, and
the TL43xxQ devices are characterized for operation
from –40°C to 125°C.

9 Detailed Description
9.1 Overview
This standard device has proven ubiquity and versatility across a wide range of applications, ranging from power
to signal path. This is due to it's key components containing an accurate voltage reference & opamp, which are
very fundamental analog building blocks. TL43xx is used in conjunction with it's key components to behave as a
single voltage reference, error amplifier, voltage clamp or comparator with integrated reference.
TL43xx can be operated and adjusted to cathode voltages from 2.5V to 36V, making this part optimum for a wide
range of end equipments in industrial, auto, telecom & computing. In order for this device to behave as a shunt
regulator or error amplifier, & gt; 1mA (Imin(max)) must be supplied in to the cathode pin. Under this condition,
feedback can be applied from the Cathode and Ref pins to create a replica of the internal reference voltage.
Various reference voltage options can be purchased with initial tolerances (at 25°C) of 0.5%, 1%, and 2%. These
reference options are denoted by B (0.5%), A (1.0%) and blank (2.0%) after the TL431 or TL432. TL431 & TL432
are both functionaly, but have separate pinout options.
The TL43xxC devices are characterized for operation from 0°C to 70°C, the TL43xxI devices are characterized
for operation from –40°C to 85°C, and the TL43xxQ devices are characterized for operation from –40°C to
125°C.

9.3 Feature Description
TL43xx consists of an internal reference and amplifier that outputs a sink current base on the difference between
the reference pin and the virtual internal pin. The sink current is produced by the internal Darlington pair, shown
in the above schematic (Figure 24). A Darlington pair is used in order for this device to be able to sink a
maximum current of 100 mA.
When operated with enough voltage headroom (≥ 2.5 V) and cathode current (IKA), TL431 forces the reference
pin to 2.5 V. However, the reference pin can not be left floating, as it needs IREF ≥ 4 µA (please see Electrical
Characteristics, TL431C, TL432C). This is because the reference pin is driven into an npn, which needs base
current in order operate properly.
When feedback is applied from the Cathode and Reference pins, TL43xx behaves as a Zener diode, regulating
to a constant voltage dependent on current being supplied into the cathode. This is due to the internal amplifier
and reference entering the proper operating regions. The same amount of current needed in the above feedback
situation must be applied to this device in open loop, servo or error amplifying implementations in order for it to
be in the proper linear region giving TL43xx enough gain.
Unlike many linear regulators, TL43xx is internally compensated to be stable without an output capacitor
between the cathode and anode. However, if it is desired to use an output capacitor Figure 24 can be used as a
guide to assist in choosing the correct capacitor to maintain stability.
9.4 Device Functional Modes
9.4.1 Open Loop (Comparator)
When the cathode/output voltage or current of TL43xx is not being fed back to the reference/input pin in any
form, this device is operating in open loop. With proper cathode current (Ika) applied to this device, TL43xx will
have the characteristics shown in Figure 23. With such high gain in this configuration, TL43xx is typically used as
a comparator. With the reference integrated makes TL43xx the prefered choice when users are trying to monitor
a certain level of a single signal.
9.4.2 Closed Loop
When the cathode/output voltage or current of TL43xx is being fed back to the reference/input pin in any form,
this device is operating in closed loop. The majority of applications involving TL43xx use it in this manner to
regulate a fixed voltage or current. The feedback enables this device to behave as an error amplifier, computing
a portion of the output voltage and adjusting it to maintain the desired regulation. This is done by relating the
output voltage back to the reference pin in a manner to make it equal to the internal reference voltage, which can
be accomplished via resistive or direct feedback.

10.2.1.2 Detailed Design Procedure
When using TL431 as a comparator with reference, determine the following:
• Input Voltage Range
• Reference Voltage Accuracy
• Output logic input high and low level thresholds
• Current Source resistance
10.2.1.2.1 Basic Operation
In the configuration shown in Figure 25 TL431 will behave as a comparator, comparing the VREF pin voltage to
the internal virtual reference voltage. When provided a proper cathode current (IK), TL43xx will have enough
open loop gain to provide a quick response. This can be seen in Figure 26, where the RSUP=10 kΩ (IKA=500 µA)
situation responds much slower than RSUP=1 kΩ (IKA=5 mA). With the TL43xx's max Operating Current (IMIN)
being 1 mA, operation below that could result in low gain, leading to a slow response.
10.2.1.2.1.1 Overdrive
Slow or inaccurate responses can also occur when the reference pin is not provided enough overdrive voltage.
This is the amount of voltage that is higher than the internal virtual reference. The internal virtual reference
voltage will be within the range of 2.5 V ±(0.5%, 1.0% or 1.5%) depending on which version is being used. The
more overdrive voltage provided, the faster the TL431 will respond.
For applications where TL431 is being used as a comparator, it is best to set the trip point to greater than the
positive expected error (i.e. +1.0% for the A version). For fast response, setting the trip point to & gt; 10% of the
internal VREF should suffice.
For minimal voltage drop or difference from Vin to the ref pin, it is recommended to use an input resistor & lt; 10kΩ
to provide Iref.

10.2.1.2.2 Output Voltage and Logic Input Level
In order for TL431 to properly be used as a comparator, the logic output must be readable by the receiving logic
device. This is accomplished by knowing the input high and low level threshold voltage levels, typically denoted
by VIH & VIL.
As seen in Figure 26, TL431's output low level voltage in open-loop/comparator mode is ~2 V, which is typically
sufficient for 5V supplied logic. However, would not work for 3.3 V & 1.8 V supplied logic. In order to accomodate
this a resistive divider can be tied to the output to attenuate the output voltage to a voltage legible to the
receiving low voltage logic device.
TL431's output high voltage is equal to VSUP due to TL431 being open-collector. If VSUP is much higher than the
receiving logic's maximum input voltage tolerance, the output must be attenuated to accomadate the outgoing
logic's reliability.
When using a resistive divider on the output, be sure to make the sum of the resistive divider (R1 & R2 in
Figure 25) is much greater than RSUP in order to not interfere with TL431's ability to pull close to VSUP when
turning off.
10.2.1.2.2.1 Input Resistance
TL431 requires an input resistance in this application in order to source the reference current (IREF) needed from
this device to be in the proper operating regions while turing on. The actual voltage seen at the ref pin will be
VREF=VIN-IREF*RIN. Since IREF can be as high as 4 µA it is recommended to use a resistance small enough that
will mitigate the error that IREF creates from VIN.

10.2.2.2 Detailed Design Procedure
When using TL431 as a Shunt Regulator, determine the following:
• Input Voltage Range
• Temperature Range
• Total Accuracy
• Cathode Current
• Reference Initial Accuracy
• Output Capacitance
10.2.2.2.1
Programming Output/Cathode Voltage
In order to program the cathode voltage to a regulated voltage a resistive bridge must be shunted between the
cathode and anode pins with the mid point tied to the reference pin. This can be seen in Figure 27, with R1 & R2
being the resistive bridge. The cathode/output voltage in the shunt regulator configuration can be approximated
by the equation shown in Figure 27. The cathode voltage can be more accuratel determined by taking in to
account the cathode current:
Vo=(1+R1/R2)*VREF-IREF*R1
In order for this equation to be valid, TL43xx must be fully biased so that it has enough open loop gain to mitigate
any gain error. This can be done by meeting the Imin spec denoted in Electrical Characteristics, TL431C,
TL432C.

10.2.2.2.2 Total Accuracy
When programming the output above unity gain (VKA=VREF), TL43xx is susceptible to other errors that may effect
the overall accuracy beyond VREF. These errors include:
•
•
•
•
R1 and R2 accuracies
VI(dev) - Change in reference voltage over temperature
ΔVREF / ΔVKA - Change in reference voltage to the change in cathode voltage
|zKA| - Dynamic impedance, causing a change in cathode voltage with cathode current
Worst case cathode voltage can be determined taking all of the variables in to account. Application note Setting
the Shunt Voltage on an Adjustable Shunt Regulator (SLVA445) assists designers in setting the shunt voltage to
achieve optimum accuracy for this device.
10.2.2.2.3 Stability
Though TL43xx is stable with no capacitive load, the device that receives the shunt regulator's output voltage
could present a capacitive load that is within the TL43xx region of stability, shown inFigure 16 and Figure 18.
Also, designers may use capacitive loads to improve the transient response or for power supply decoupling.
When using additional capacitance between Cathode and Anode, refer to Figure 16 and Figure 18. Also,
application note Understanding Stability Boundary Conditions Charts in TL431, TL432 Data Sheet (SLVA482) will
provide a deeper understanding of this devices stability characteristics and aid the user in making the right
choices when choosing a load capacitor.
10.2.2.2.4 Start-Up Time
As shown in Figure 28, TL43xx has a fast response up to ~2 V and then slowly charges to it's programmed
value. This is due to the compensation capacitance (shown in Figure 24) the TL43xx has to meet it's stability
criteria. Despite the secondary delay, TL43xx still has a fast response suitable for many clamp applications.

11 Power Supply Recommendations
When using TL43xx as a Linear Regulator to supply a load, designers will typically use a bypass capacitor on the
output/cathode pin. When doing this, be sure that the capacitance is within the stability criteria shown in
Figure 16 and Figure 18.
In order to not exceed the maximum cathode current, be sure that the supply voltage is current limited. Also, be
sure to limit the current being driven into the Ref pin, as not to exceed it's absolute maximum rating.
For applications shunting high currents, pay attention to the cathode and anode trace lengths, adjusting the width
of the traces to have the proper current density.
12 Layout
12.1 Layout Guidelines
Bypass capacitors should be placed as close to the part as possible. Current-carrying traces need to have widths
appropriate for the amount of current they are carrying; in the case of the TL43xx, these currents will be low.

13.6 Electrostatic Discharge Caution
This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
