IR3080MPBF

The IR3080 Control IC combined with an IR XPhaseTM Phase IC provides a full featured and flexible way to implement a complete VRD 10 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.
