摘要

本文提出了一种低电压、低功耗DC-DC变换器的优化设计，该变换器采用小尺寸电感(1 /spl mu/H)，具有控制器和集成CMOS开关。通过对单片DC/DC变换器导通损耗和开关损耗的分析，实现了单片DC/DC变换器的优化设计。通过损耗分析，得出在几种DC-DC变换器中，带同步整流的恒频硬开关PWM变换器最适合低压低功耗应用。

An integrated CMOS DC-DC converter for battery-operated systems

This paper presents an optimum design for a low-voltage, low-power DC-DC converter which has a controller and integrated CMOS switches using a small size inductor (1 /spl mu/H). Optimum design for the single chip DC/DC converter is achieved by analyzing the amount of conduction and switching losses. Through the loss analyses, it turns out that a constant frequency hard switching PWM converter with synchronous rectifier is most suitable among the several kinds of DC-DC converters for low voltage and low power applications.
