DESCRIPTION

The IR3092 Control IC provides a full featured, single chip solution to implement robust power conversion solutions for three different microprocessor families; 1) AMD Opteron, 2) AMD Athlon or 3) Intel VR10.X family of processors. The user can select the appropriate VID range with a single pin. PWM Control and 2 phase gate drive functions are integrated into a single IC. In addition to CPU power, the IR3092 offers a compact, efficient solution for high current POL converters.
