NCP1200AP100

Product Summary

The NCP1200AP100 is a PWM Current-Mode Controller for Universal Off-Line Supplies Featuring Low Standby Power. Housed in SOIC-8 or PDIP-8 package, the NCP1200AP100 enhances the previous NCP1200 series by offering a reduced optocoupler current together with an increased drive capability. Due to its novel concept, the circuit allows the implementation of complete off line AC.DC adapters, battery charger or a SMPS where standby power is a key parameter. With an internal structure operating at a fixed 40 kHz, 60 kHz or 100 kHz, the controller supplies itself from the high voltage rail, avoiding the need of an auxiliary winding. This feature naturally eases the designer task in battery charger applications. Finally, current mode control provides an excellent audio susceptibility and inherent pulse by pulse control. The applications of the NCP1200AP100 include AC-DC Adapters for Portable Devices, Offline Battery Chargers, Auxiliary Power Supplies (USB, Appliances, TVs, etc.).
