Description

The NCP1200AD60R is a PWM Current-Mode Controller for Universal Off-Line Supplies, specifically designed for AC DC Converters and Offline Switchers. It is housed in a SOIC−8 or PDIP−8 package and offers a reduced optocoupler current with increased drive capability. With its novel concept, this component allows for the implementation of complete off−line AC−DC adapters, battery chargers, or a SMPS where standby power is a key parameter.
