Description

The IR3084A Control IC combined with an IR XPhaseTM  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 multiphase  converter.  The  XPhaseTM  architecture of the IR3084A results  in  a  power  supply  that  is  smaller,  less expensive, and easier to design while providing higher efficiency than conventional approaches.
