摘　　要：交流-直流(AC-DC)电源适配器的应用非常广泛,但由于长时间处于空载待机模式,而且使用量巨大,由此带来巨大的电能损耗。利用NCP1246+NCP4354实现的低待机能耗解决方案,可轻松降低空载能耗,适用于功率65 W的电源适配器,并能实现20mW以下的极低待机能耗。The AC-DC power adapter is widely used. However, its large consumption and being no-load standby mode for a long time results in huge electrical energy loss. The solution of low standby loss with NCP1246＋NCP4354 can decrease the no load energy loss easily, applied to power adapter with 65W, realizing extremely low standby loss under 20mW.
