Abstract :
This paper presents the performance and design of a variable frequency 30W, 48V/1.5V voltage regulator module (VRM) for stand-alone high-end servers, laptop computers, and flash memory applications. Self-sustained oscillation control (SSOC) operation is used to achieve voltage regulation and high efficiency for a wide range of load currents. It is a current mode controller for resonant converters, hence offers lower power component ratings than the conventional variable frequency controller and very fast transient response as well. Analytical, simulation and experimental results are presented to offer the proof of concept
