DATA SHEET

XPHASE3^TMDUAL PHASE IC

DESCRIPTION

The IR3527 Dual Phase IC combined with an IR XPhase3^TMControl IC provides a full featured and flexible

way to implement multiphase power solutions. The Control IC provides overall system control and interfaces

with any number of IR3527 Phase ICs which each drive and monitor 2 phases of a Synchronous Buck

converter.

The IR3527 implement an independent power savings function for each power stage and sequential phase

timing for use in single output multiphase converters. When power saving mode is enabled, the power stage

will disable its output thus eliminating its switching loss while proper converter operation is maintained by the

single power stage or in conjunction with other converter power stages. The IR3527 current sense amplifiers

remain active when in power savings to support adaptive voltage positioning.

FEATURES

7V/1.3A gate drivers (2.6A GATEL sink current)

Converter output voltage up to 5.1 V (Limited to VCCL-1.4V)

Loss-less inductor current sensing

Feed-forward voltage mode control

Integrated boot-strap synchronous PFET

Self-calibration of PWM ramp, current sense amplifier, and current share amplifier

Single-wire bidirectional average current sharing

Only three external components per phase, plus common decoupling capacitors

Power State Indicator (PSI) interface provides the capability to maximize the efficiency at light loads.

Debugging function isolates phase from the converter

Small thermally enhanced 24L 4 x 4mm MLPQ package

RoHS compliant
