NCP1200A .. PWM Current- Mode Controller for Universal Off- Line Supplies Featuring Low Standby Power Housed in SOIC- 8 or PDIP- 8 package, the NCP1200A 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 plete 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...
