onsemi NCP1000/NCP1001/NCP1002 Integrated Off-Line Switching Regulator Datasheet
The NCP1000 through NCP1002 series of integrated switching regulators combine a fixed frequency PWM controller with an integrated high voltage power switch circuit. This chip allows for simple design and minimal parts count for very low cost applications which utilize an ac input. This chip is designed to power a single ended topology, typically a discontinuous mode flyback, with secondary side sensing.
