NCP1382 Overview
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...
