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’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.
FEATURES
x 5 bit or 6 bit VID with 0.5% overall system accuracy
x Selectable VID Code for AMD Opteron or Athlon or Intel VR10.X
