IR3092
DATA SHEET
2 PHASE OPTERON, ATHLON, OR VR10.X CONTROL IC
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.
