IR3086
XPHASE TM PHASE IC WITH OVP, FAULT AND OVERTEMP DETECT
DESCRIPTION
The IR3086 Phase IC combined with an IR XPhase 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 XPhase TM architecture results in a power supply that is smaller, less
expensive, and easier to design while providing higher efficiency than conventional approaches.
