Abstract

To achieve higher power density and design flexibility with unlimited phase number, the concept of monolithic/modularized voltage regulator channel (MVRC) is introduced to be a generic power integrated circuit (IC) solution for both central processing unit (CPU) and point-of-load (POL) power management. Novel control architecture and analog circuits are invented to implement the MVRC concept. Tolerance analysis and hardware testing verified that the MVRC approach is suitable for today´s and even future´s microprocessor power management.
