本应用笔记将描述对DC / DC降压转换器的主要动态行为的评估。 所描述的测试程序和测量结果将确定转换器是否以安全方式运行，以及转换器是否满足启动时间，浪涌电流，峰值电感器电流，电感器性能以及输出纹波和纹波谱的设计目标。

This application note will describe the evaluation ofthe main dynamic behaviors of a DC/DC buckconverter. The test procedures and measurementsdescribed will determine whether the converteroperates in a safe manner, and whether it meets itsdesign goals for start-up time, inrush current, peakinductor current, inductor behavior, and output rippleand ripple spectrum.
