IR3564B

IR3570B

Dual Output Digital Multi-Phase Controller

FEATURES

DESCRIPTION

 Dual output 4+1 and 3+2 phase PWM

The IR3564B/70B 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.

Controllers

 Easiest layout and fewest pins in the industry

 Fully supports AMD® SVI1 & SVI2 with dual

OCP and Intel® VR12 & VR12.5

The IR3564B/70B includes IR’s Efficiency Shaping

Technology to deliver exceptional efficiency at minimum

cost across the entire load range. 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.

 Complies with VR12.5 Rev 1.3 requirement

for SVID register 15h to have <200 µSec

filter

 Overclocking & Gaming Mode

 Switching frequency from 200kHz to 2MHz

per phase

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 on-chip MTP.

 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-

The IR3564B/70B provides extensive OVP, UVP, OCP

and OTP fault protection and includes thermistor based

temperature sensing with VRHOT signal.

compensation

 Per-Loop Fault Protection: OVP, UVP, OCP,

OTP, CFP

The IR3564B/70B includes numerous features like

differentiation, simplifying VRD design and enabling

fastest time-to-market (TTM) with “set-and-forget”

methodology.

 I2C/SMBus/PMBus system interface for

telemetryof Temperature, Voltage, Current &

Power for both loops

 Multiple Time Programming (MTP) with

integrated charge pump for easy custom

configuration

APPLICATIONS

 Compatible with IR ATL and 3.3V tri-state

 AMD® SVI1 & SVI2, Intel® VR12 & VR12.5 based

Drivers

systems

 +3.3V supply voltage; -40°C to 85°C ambient

 Desktop & Notebook CPU VRs

 GPU & Memory VRs

operation

 Pb-Free, RoHS, 5x5mm, 40-pin, 0.4mm pitch
