NCP1377 PWM Current-Mode Controller

NCP1377 Description

NCP1377, NCP1377B PWM Current-Mode Controller for Free-Running Quasi-Resonant Operation The NCP1377 combines a true current mode modulator and a dema.
Pin Symbol Function 1 Demag Core reset detection and OVP 2 FB Sets the peak current setpoint 3 CS Current sense input and skip cycle level.

NCP1377 Features

* 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
