直流-直流转换器设计指南AN607 Vishay Siliconix DC-to-DC Design Guide Serge Jaunay, Jess Brown INTRODUCTION Manufacturers of electronic systems that require power conversion are faced with the need for higher-density dc-to-dc converters that perform more efficiently, within a smaller footprint, and at lower cost―despite increasing output loads. To meet these demands, Siliconix has combined advanced TrenchFETR and PWM-optimized process technologies, along with innovative new packages, to provide: D lowest on-resistance for minimum power dissipation D lowest gate charge for minimum switching losses D dV/dt shoot-through immunity1 D improved thermal management. Breakthroughs in thermal management for increasing power density are being achieved with Vishay Siliconix packaging technologies such as the PowerPAKt (Si7……
