  • Abstract
    This paper starts with the two-stage Voltage-Regulator (VR) solution for future server microprocessors. By using two-stage solution, high efficiency and high power density VR can be put as close as the microprocessor to eliminate the interconnection effect. Then, high efficiency high power density voltage divider which is served as the 1st stage is analyzed and optimal design is illustrated. Finally, a 2500 W/in3 interleaved voltage divider with 97~98% efficiency is experimentally verified.
