IR3084
DESCRIPTION
VR 10/11 CONTROL IC
The IR3084 Control IC bined with an IR XPhase TM Phase IC provides a full featured and flexible way to implement a plete VR10 or VR11 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 XPhase TM architecture results in a power supply that is smaller, less expensive, and easier to design while providing higher efficiency than conventional approaches.
