IR3093
DATA SHEET
3 PHASE OPTERON, ATHLON, OR VR10.X CONTROL IC
DESCRIPTION
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鈥檚 Opteron, 2) AMD鈥檚
Athlon or 3) Intel鈥檚 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.
