NCP1337ADAPGEVB:NCP1271 57 W Adapter Evaluation Board
The NCP1271ADAPEVB is an example circuit using NCP1271 (65 kHz version) in flyback topology. The 19 V, 3.0 A circuit delivers above 85% from universal input (85 to 265 Vac). The no load standby consumption is 83 mW at 230 Vac. The NCP1271 is one of the latest fixed-frequency current-mode PWM switching controllers with (1) soft-skip standby operation for low-level audible noise (2) integrated high-voltage startup for saving PCB space and power (3) adjustable skip level to minimize standby power and (4) optional external latch protection features.
