www.DataSheet4U.com IR3087 DATA SHEET XPHASETM PHASE IC WITH OPTI-PHASETM, OVP, AND OVERTEMP DETECT DESCRIPTION The IR3087 Phase IC combined with an IR XPhaseTM 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. The IR3087 with Opti-PhaseTM is intended for applications demanding increased efficiency under medium to light load conditions.
