IR3086APBF Datasheet | International Rectifier

DESCRIPTION The IR3086APb F Phase IC bined 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. ..
