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

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 damage to the system. The IC only restarts when the user cycles the mains power supply. With the low power int
