Abstract :
To achieve higher power density and design flexibility with unlimited phase number, the concept of MVRC (monolithic/modularized voltage regulator channel) is introduced to be a generic power IC solution for both CPU and POL (point of load) 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
