IR3080 Overview
The IR3080 Control IC bined with an IR XPhaseTM Phase IC provides a full featured and flexible way to implement a plete 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...
