IR3093MTRPBF

The IR3093 Control IC provides a full featured, cost effective, single chip solution to implement robust power conversion solutions for three different microprocessor families; 1) AMD’s Opteron, 2) AMD’s Athlon or 3) Intel’s VR-10.X family of processors.
The user can select the appropriate VID range with a single pin. Control and 3 phase Gate Drive functions are integrated into a single cost effective IC. . In addition to CPU power, the IR3093 offers a compact, efficient solution for high current POL converters.
