具有低压线路输入和 12V/25mA 输出的交流/直流降压转换器参考设计
The PMP20654 reference design uses Buck converter to convert low line AC input voltage (85Vac to 140Vac) to a 12V/25mA DC output with UCC28880 FET integrated controller. This design passes class B conducted emission test without adding any EMI filter before rectifier.
