DATA SHEET
XPHASE3 TM PHASE IC
DESCRIPTION
The IR3507Z Phase IC combined with an IR XPhase3 TM Control 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 TM architecture results in a power supply that is smaller, less
expensive, and easier to design while providing higher efficiency than conventional approaches.

Power State Indicator (PSI) interface provides the capability to maximize the efficiency at light loads.
7V/2A gate drivers (4A 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
Only four external components per phase
3 wire analog bus connects Control and Phase ICs (VID, Error Amp, IOUT)
3 wire digital bus for accurate daisy-chain phase timing control without external components
Anti-bias circuitry prevents excessive sag in output voltage during PSI de-assertion
PSI input is ignored during power up
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 20L 4 X 4mm MLPQ package
RoHS compliant
