Datasheet Summary
PWM Current- Mode Controller for Universal Off- Line Supplies Featuring Low Standby Power with Fault Protection Modes
Housed in SOIC--8 or PDIP--8 package, the NCP1201 enhances the previous NCP1200 series by offering a reduced optocoupler current with additional Brownout Detection Protection (BOK). Similarly, the circuit allows the implementation of plete off--line AC--DC adapters, battery chargers or Switchmode Power Supplies (SMPS) where standby power is a key parameter.
The NCP1201 Features efficient protection circuitry. When in the presence of a fault (e.g. failed optocoupler, overcurrent condition, etc.) the control permanently disables the output pulses to avoid...
