Overview

NCP1201 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 complete 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 subsequent...
