摘要

DC/DC转换器的启动问题可能会有问题，甚至导致整个系统故障。本文介绍了DC/DC变换器设计过程中遇到的一些问题，并提出了解决方案。第一个解决方案使用一个修改的驱动程序，它限制了启动期间的加载电流。第二种方案采用改进的无源开关软启动[1]，该方案基于线性充电电容和带D触发器的输出电压检测器。所描述的解决方案是采用CMOS 110纳米技术设计和制造的。

DC/DC Buck Converter Soft-Start Methods

Startup issues of DC/DC converters can be problematic, and even cause malfunction of the whole system. In this paper selected problems encountered during the DC/DC converter design process are described and solutions are provided. The first solution uses a modified driver, which limits the loading current during startup. The second solution uses a modified passive switch soft start [1], which based on linearly charged capacitance and output voltage detector with D flip-flop. The described solutions have been designed and fabricated using CMOS 110 nm technology.
