The Intel Core i7 power management design is a complete solution for the Intel™ IMVP-7 Serial VID (SVID) Power System The design features an IMVP-7 3-Phase CPU supply, a single-phase GPU Vcore supply, a 1.05VCCIO supply, and a DDR3L/DDR4 memory rail. To greatly improve power density and thermal performance, TI's 5-mm x 6mm NEXFET Power Block MOSFETs are used.

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