DATA SHEET

XPHASE3^TMCONTROL IC

DESCRIPTION

The IR3502A control IC combined with an XPHASE3^TMPhase IC provides a full featured and flexible way

to implement a complete VR11.0 and VR11.1 power solution. The IR3502A provides overall system control

and interfaces with any number of Phase ICs, each driving and monitoring a single phase. The XPhase3^TM

architecture results in a power supply that is smaller, less expensive, and easier to design while providing

higher efficiency than conventional approaches.

FEATURES



1 to X phase operation with matching Phase IC

0.5% overall system set point accuracy

Daisy-chain digital phase timing provides accurate phase interleaving without external components

Programmable 250kHz to 9MHz clock oscillator frequency provides per phase switching frequency of

250kHz to 1.5MHz



Programmable Dynamic VID Slew Rate

Programmable VID Offset or No Offset

Programmable Load Line Output Impedance

High speed error amplifier with wide bandwidth of 30MHz and fast slew rate of 10V/us

Programmable constant converter output current limit during soft start

Hiccup over current protection with delay during normal operation

Central over voltage detection and latch with programmable threshold and communication to phase ICs

Over voltage signal output to system with overvoltage detection during powerup and normal operation

Load current reporting

Single NTC thermistor compensation for correct current reporting, OC Threshold, and Droop

Detection and protection of open remote sense line

Open control loop protection

IC bias linear regulator controller

Programmable VRHOT function monitors temperature of power stage through a NTC thermistor

Remote sense amplifier with true converter voltage sensing

Small thermally enhanced 32L 5mm x 5mm MLPQ package

RoHS Compliant
