NCP1338 Description
PWM Current-Mode Controller for Free Running Quasi-Resonant Operation NCP1338 The NCP1338 bines a true current mode modulator and a demagnetization detector which ensures full Borderline/Critical Conduction Mode in any load/line conditions together with minimum drain voltage switching (Quasi−Resonant operation). The transformer core reset detection is done internally, without using any external signal, due to the...
