IR3092 - 2-PHASE CONTROLLER

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.

Features

  • x 5 bit or 6 bit VID with 0.5% overall system accuracy x Selectable VID Code for AMD Opteron, AMD Athlon or Intel VR10.X x Programmable Slew Rate response to “On-the-Fly” VID Code Changes x 3.5A Gate Drive Capability x Programmable 100KHz to 540KHz oscillator x Programmable Voltage Positioning (can be disabled) x Programmable Softstart x Programmable Hiccup Over-Current Protection with Delay to prevent false triggering x Simplified Powergood provides indication of proper operation and avoids fal.
