IR3081 XPHASE VR 10.0 CONTROL IC

The IR3081 Control IC combined with an IR XPhaseTM Phase IC provides a full featured and flexible way to implement a complete VR 10.0 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.
