IR3081A Datasheet Xphasetm Vr 10 Control Ic

Manufacturer: International Rectifier (now Infineon)

Overview: IR3081A DATA SHEET XPHASETM VR 10 CONTROL IC.

General Description

The IR3081A Control IC combined with an IR XPhaseTM Phase IC provides a full featured and flexible way to implement a complete VR 10 power solution.

The “Control” IC provides overall system control and interfaces with any number of “Phase ICs” which each drive and monitor a single phase of a multiphase converter.

The XPhaseTM architecture results in a power supply that is smaller, less expensive, and easier to design while providing higher efficiency than conventional approaches.

Key Features

  • 6 bit VR 10 compatible VID with 0.5% overall system accuracy 1 to X phases operation with matching phase ICs Programmable Dynamic VID Slew Rate No Discharge of output capacitors during Dynamic VID step-down (can be disabled) +/-300mV Differential Remote Sense Programmable 150kHz to 1MHz oscillator Programmable VID Offset and Load Line output impedance Progra.
