Today's need for higher power density combined with higher efficiency has driven many changes in the non-isolated point-of-load regulator. This paper explains how the ZVS Buck Regulator removes barriers to increased power throughput in wide input range point-of-load applications. Subjects covered include simulation models for size reduction and increased power throughput; how the high frequency Zero-Voltage Switching (ZVS) topology helps enable efficiency; and how to approach the three fundamental challenges of hard switching, body diode conduction and gate drive loss.
