Overview
IR3084U XPHASE DESCRIPTION The IR3084U Control IC combined with an IR XPhaseTM Phase IC provides a full featured and flexible way to implement a complete VR10, VR11, Opteron, or Athlon64 power solution.
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 IR3084U is based on the IR3084 VR10 Control IC, but incorporates the following modifications; • • • • • • • • Supports VR11 7-bit VID, VR10 7-bit extended VI...
