Dual Output Digital Multi-Phase Controller
FEATURES
IR3567B
DESCRIPTION
Dual output 6+2 phase PWM Controller
The IR3567B is a dual-loop digital multi-phase buck
controller designed for CPU voltage regulation and is
fully compliant with AMD® SVI1 & SVI2 and Intel©
VR12 & VR12.5 specifications.
Easiest layout and fewest pins in the industry
Fully supports AMD® SVI1 & SVI2 with dual
OCP and Intel® VR12 & VR12.5
Complies with VR12.5 Rev 1.3 requirement for
SVID register 15h to have & lt; 200 µSec filter
Overclocking & Gaming Mode
Switching frequency from 200kHz to 2MHz
per phase
IR Efficiency Shaping Features including
Dynamic Phase Control and Automatic Power
State Switching
IR Adaptive Transient Algorithm (ATA) on both
loops minimizes output bulk capacitors and
system cost
Auto-Phase Detection with auto-compensation
Per-Loop Fault Protection: OVP, UVP, OCP,
OTP, CFP
I2C/SMBus/PMBus system interface for
telemetry of Temperature, Voltage, Current &
Power for
both loops
The IR3567B includes IR’s Efficiency Shaping
Technology to deliver exceptional efficiency at
minimum cost across the entire load range. IR Variable
Gate Drive optimizes the MOSFET gate drive voltage
based on real-time load current. IR’s Dynamic Phase
Control adds/drops active phases based upon load
current and can be configured to enter 1-phase
operation and diode emulation mode automatically or
by command.
IR’s unique Adaptive Transient Algorithm (ATA), based
on proprietary non-linear digital PWM algorithms,
minimizes output bulk capacitors and Multiple Time
Programmable (MTP) storage saves pins and enables
a small package size. Device configuration and fault
parameters are easily defined using the IR Digital
Power Design Center (DPDC) GUI and stored in onchip MTP.
The IR3567B provides extensive OVP, UVP, OCP and
OTP fault protection and includes thermistor based
temperature sensing with VRHOT signal.
Multiple Time Programming (MTP) with
integrated charge pump for easy custom
configuration
The IR3567B includes numerous features like register
diagnostics for fast design cycles and platform
differentiation, simplifying VRD design and enabling
fastest time-to-market (TTM) with “set-and-forget”
methodology.
Compatible with IR ATL and 3.3V tri-state
Drivers
+3.3V supply voltage; -40°C to 85°C ambient
operation
Pb-Free, RoHS, 7x7mm, 56-pin, 0.4mm pitch
