IR3084A XPHASE TM VR 10/11 CONTROL IC

The IR3084A Control IC combined with an IR XPhase Phase IC provides a full featured and flexible way to implement a complete 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 TM multiphase converter. The XPhase architecture results in a .
