NCP1378 Product details

Description

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 selection 4 GND 5 Drv 6 VCC 7 NC 8 HV The IC ground Driving pulses Supplies the IC -- High--voltage pin Description The auxiliary FLYBACK signal ensures discontinuous operation and offers a fixed overvoltage detection level of 5.2 V.By connecting an optocoupler to this pin, the peak current setpoint is adjusted accordingly to the output power deman

Features

an efficient protective circuitry that, 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- recovers. Finally an internal 1.0 ms Soft- Start eliminates the traditional startup stress. The NCP1378 is tailored for low voltage.
