Design files

Overview

The Intel® Core i7 power management design is a reference design for the Intel® IMVP-7 Serial VID (SVID) power system. This design features an IMVP-7 3-phase CPU supply, a single-phase GPU Vcore supply, a 1.05-VCC IO supply, and a DDR3L/DDR4 memory rail. To greatly improve power density and thermal performance, 5-mm x 6mm NEXFET power block MOSFETs are used.

Features
  • Design supports a 9-20V input from Vbatt
  • Small high-density power solution for Sandy Bridge
  • 3-phase CPU supply supports up to 94 A
  • 90% peak (80% full-load) efficiency from 12 Vin to 1.05 Vout - CPU supply
  • Low CPU supply ripple: 25 mV
  • Design has been built and tested, and there is a board available

 

A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
