Datasheet Summary
Self-Supplied Monolithic Switcher for Low StandbyPower Offline SMPS
The NCP1015 integrates a fixed- frequency current- mode controller and a 700 V voltage MOSFET. Housed in a PDIP- 7 or SOT- 223 package, the NCP1015 offers everything needed to build a rugged and low- cost power supply, including soft- start, frequency jittering, short- circuit protection, skip- cycle, a maximum peak current set- point and a Dynamic Self- Supply (no need for an auxiliary winding).
Unlike other monolithic solutions, the NCP1015 is quiet by nature: during nominal load operation, the part switches at one of the available frequencies (65- 100 kHz). When the current set- point falls below a given value, e.g. the...
