XPHASE3TM PHASE IC
DESCRIPTION
The IR3505 Phase IC combined with an IR XPhase3TM 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 XPhase3TM architecture 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
