IR3507 - International Rectifier

IR3507 PHASE

The IR3507 Phase IC combined with an IR XPhase3 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 TM phase of a multiphase converter. The XPhase3 a.
