摘要
介绍了新型开关芯片TNY277P的性能特点及工作原理,叙述了其在多路输出开关电源设计中的具体应用。同时对如何选用及设计开关电源中的其它主要元件进行了描述,经效果评估可知,该电源系统可得到更稳定、纹波更小的输出电压。
Introduction was made to characteristics and working principle of the new type chip TNY277P,whose concrete application in multiplex output switched-mode power supply（SMPS） was discussed. At the same time description was made on how to select and design other components in the SMPS. Performance evaluation shows that this SMPS can output more reliable voltage with smaller ripples.
