NCP1377, NCP1377B PWM Current-Mode Controller for Free-Running Quasi-Resonant Operation The NCP1377 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).
Due to its inherent skip cycle capability, the controller enters burst mode as soon as the power demand falls below a predetermined level.
As this happens at low pe

* a sampling time of 4.5 ms whereas it is 1.5 ms for the B version. The NCP1377 also features an efficient protective circuitries which, in presence of an overcurrent condition, disables the output pulses and enters a safe burst mode, trying to restart. Once the default has gone, the device auto
