NCP1381, NCP1382 Low- Standby High Performance PWM Controller Housed in a SO 14 package, the NCP1381/82 includes everything needed to build rugged and efficient Quasi Resonant (QR) Switching Power Supplies.

When powered by a front end Power Factor Correction circuitry, the NCP1381/82 automatically disconnects the PFC controller in low output loading conditions (with an adjustable level), thus improving the standby power.

This is particularly well suited for medium to high

NCP1382 Features

* several efficient protection options like a) a short

* circuit / overload detection independent of the auxiliary voltage b) an auto

* recovery brown

* out detection and c) an input to externally latch the circuit in case of Overvoltage Protection or Over Temperature Protection. Fea
