IR3080 Datasheet Xphase Vrd10 Controller

Manufacturer: International Rectifier (now Infineon)

Overview: Data Sheet No. PD94705 IR3080 XPHASETM VRD10 CONTROL IC WITH VCCVID & OVERTEMP.

General Description

The IR3080 Control IC combined with an IR XPhaseTM Phase IC provides a full featured and flexible way to implement a complete VRD 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 VR10 compatible VID with 0.5% overall system accuracy.
  • 1 to X phases operation with matching phase ICs.
  • On-chip 700Ω VID Pull-up resistors with VID pull-up voltage input.
  • 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.
