ICs Set To Tackle Core Power Needs Of Next-Generation CPUs

Consisting of main controllers and FET drivers, a new family of chipsets has been developed for use in meeting next-generation CPU core power requirements. The chipsets are said to feature the industry’s most advanced phase-to-phase current balance and reference voltage tolerance, providing a two- to four-phase architecture and optimizing dc-to-dc converter designs spanning a 35A to 100A range. The chipset family includes three multiphase controllers (HIP6301/6302/6303) and three gate drivers (HIP6601/6602/6603). A total core-voltage power system can be made using a set plus MOSFETs. Evaluation boards are offered for AMD’s Athlon and Intel’s Willamette CPUs.
