NCP1010 - Self-Supplied Monolithic Switcher for Low ...

1 Semiconductor Components Industries, LLC, 2014 October, 2016 Rev. 241 Publication Order Number: NCP1010 /DNCP1010, NCP1011,NCP1012, NCP1013,NCP1014 Self-Supplied MonolithicSwitcher for Low Standby-Power Offline SMPSThe NCP101X series integrates a fixed frequency current modecontroller and a 700 V MOSFET. Housed in a PDIP 7 or SOT 223package, the NCP101X offers everything needed to build a rugged andlow cost power supply, including soft start, frequency jittering,short circuit protection, skip cycle, a maximum peak current setpointand a Dynamic self Supply (no need for an auxiliary winding).

2 Unlike other Monolithic solutions, the NCP101X is quiet by nature:during nominal load operation, the part switches at one of the availablefrequencies (65 100 130 kHz). When the current setpoint fallsbelow a given value, the output power demand diminishes, the ICautomatically enters the so called skip cycle mode and providesexcellent efficiency at light loads. Because this occurs at typically 1/4of the maximum peak value, no acoustic noise takes place. As a result,standby power is reduced to the minimum without acoustic circuit detection takes place when the feedback signal fadesaway, in true short circuit conditions or in broken Optocouplercases.

3 External disabling is easily done either simply by pulling thefeedback pin down or latching it to ground through an inexpensiveSCR for complete latched off. Finally soft start and frequencyjittering further ease the designer task to quickly develop low cost androbust offline power improved standby performance, the connection of an auxiliarywinding stops the DSS operation and helps to consume less than100 mW at high line. In this mode, a built in latched overvoltageprotection prevents from lethal voltage runaways in case theOptocoupler would brake.
