DATA SHEET
XPHASE TM PHASE IC WITH OVP, FAULT AND OVERTEMP DETECT
DESCRIPTION
The IR3086A Phase IC combined with an IR XPhase
TM
Control IC provides a full featured and flexible way
phase of a multiphase converter. The XPhase
architecture results in a power supply that is smaller, less
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
TM
expensive, and easier to design while providing higher efficiency than conventional approaches.
