摘要
介绍了 UC3842在单端反激式 PWM 型开关电源中的应用。在对 UC3842常用的三种电压反馈电路分析的基础上,设计了一种新的电压反馈电路,实验证明了这种新的电压反馈电路具有很好的稳压效果。
The applications of UC3842 in single-ended flyback PWM SMPS are introduced.Based on the analysis of three voltage feedback circuts which are usually used,a novel voltage feedback circuit is designed,which circuit is proved to be effcitive in practical experiment.
