DATA SHEET

XPHASE3^TMPHASE IC

DESCRIPTION

The IR3505Z Phase IC combined with an IR XPhase3^TMControl IC provides a full featured and flexible way to

implement power solutions for the latest high performance CPUs and ASICs. The “Control” IC provides

overall system control and interfaces with any number of “Phase” ICs which each drive and monitor a single

phase of a multiphase converter. The XPhase3^TMarchitecture results in a power supply that is smaller, less

expensive, and easier to design while providing higher efficiency than conventional approaches.

FEATURES

•

7V/2A gate drivers (4A GATEL sink current)

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

Support loss-less inductor current sensing

Feed-forward voltage mode control

Integrated boot-strap synchronous PFET

Only four IC related external components per phase

3 wire analog bus connects Control and Phase ICs (VDAC, Error Amp, ISHARE)

3 wire digital bus for accurate daisy-chain phase timing control without external components

Debugging function isolates phase IC from the converter

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

Single-wire bidirectional average current sharing

•

Small thermally enhanced 16L 3 x 3mm MLPQ package

RoHS compliant
