DATA SHEET
XPHASE3TM PHASE IC
DESCRIPTION
The |R35082 Phase IC combined with any IR XPhase3TU Control IC provides a full featured and flexible way
to implement a power solution 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.
The |R35082 disables its current sense amplifiers when entering power savings mode. The recommended
use for these Phase ICs is for applications without adaptive voltage positioning where two or more power
stages will be operating in power savings mode.
FEATURES |R35082 PHASE IC
Power State Indicator (PSI) interface provides the capability to maximize the efficiency at light loads.
Anti-bias circuitry
7V/2A gate drivers (4A GATEL sink current)
Support converter output voltage up to 5.1 V (Limited to VCCL-1.4V)
Loss-less inductor current sensing
Phase delay DFF bypassed during PSI assertion mode to improve output ripple performance
Over-current protection during PSI assertion mode operation
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
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
