Abstract

MOSFET performance and gate drive operation play a vital role in efficient power processing. This work studies transistor and gate drive performance in a synchronous rectifier, buck regulator for PC motherboard power management (VRM). The object is to analyze the interaction of the transistors with the drive stage under various operating conditions. Analysis of loss contributions is performed. Emphasis is placed on performance optimization, low cost, and reproducibility
