Overview
NCP1200A www.
DataSheet4U.
com 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 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...
