Product Summary

The NCP1377BDR2G is a PWM Current-Mode Controller for Free-Running Quasi-Resonant Operation. The NCP1377BDR2G combines 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).
