Description
1200AP40 is 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. […]
