一种双路隔离输出反激变换器的设计

Design of A Dual Channel Isolated Output Flyback Converter

文中基于TI的电源芯片LM5032设计了一款双路隔离输出反激变换器,介绍了反激变压器、控制回路的设计以及开关管的选择,并提示了在设计中需要注意的问题。最后通过实验数据与波形验证了本设计。

In this paper,a dual channel isolated output flyback converter was designed based on TI＇s power chip LM5032.The design of flyback transformer,control loop and selection of switch tube were introduced,and some problems needing attention in design were also indicated.Finally,the design was verified by experimental data and waveform.
