Abstract
A compact (55 W/in/sup 3/), efficient (86% power train), 1 MHz switch-mode, DC-to-DC power converter contained in a 2 in by 2 in by 0.25 in, 1 in/sup 3/ inch package is presented. The converter developed for on-card applications in distributed power processing systems, uses pulse-width modulation at a constant frequency of 1 MHz (2 MHz ripple frequency) and zero-voltage resonant transition switching. The interleaved forward topology, steady-state analysis, capacitor substrate, planar printed-wiring-board transformer, packaging, electrical performance, power loss analysis, thermal analysis, reliability, and efficiency and power density improvements are described.Keywords
