Title: MVRC ---- Monolithic/Modularized Voltage Regulator Channel
Abstract: To achieve higher power density and higher order of design flexibility with unlimited phase number, the concept of Monolithic / Modularized Voltage Regulator Channel (MVRC) is introduced as a generic power IC solution for both CPU and POL (Point Of Load) power
management. Novel control schemes and analog circuits are invented to implement the MVRC concept. They include: 1) a novel distributed interleaving scheme; 2) a distributed current sharing and Adaptive Voltage Position (AVP) scheme. Tolerance analysis and hardware testing results verify that the proposed control is suitable for today and future's microprocessor power management.
