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
