NCP1203 Datasheet | onsemi

PWM Current-Mode Controller for Universal Off-Line Supplies Featuring Standby and Short Circuit Protection Housed in SOIC- 8 or PDIP- 8 package, the NCP1203 represents a major leap toward ultra- pact Switchmode Power Supplies and represents an excellent candidate to replace the UC384X devices. Due to its proprietary SMARTMOS™ Very High Voltage Technology, the circuit allows the implementation of plete off- line AC- DC adapters, battery charger and a high- power SMPS with few external ponents. With an internal structure operating at a fixed 40 kHz, 60 kHz or 100 kHz switching frequency, the controller Features a high- voltage startup FET which ensures a clean and loss- less startup...
