IR3086 General 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 XPhaseTM architecture results in a power supply that is smaller, less expensive, and easier to design while providing higher efficiency than conventional approaches.

IR3086 Maximum Ratings

Operating Junction Temperature..........................................150
Storage Temperature Range..................................-65 to 150
ESD Rating.....................................HBM Class 1C JEDEC standard
