Abstract :
Recently, a new high-frequency resonant-converter technology with phase-shifted regulation was introduced. The new technology has proven to be a cost-effective solution for VRMs for the next generation of microprocessor systems. The new technology is employed in the development of a 1.8-MHz, 48-V, 130-W (0.95-1.7 V, 100 A) resonant VRM. Fundamentals of the new technology are reviewed. Implementation details and experimental results are given
