NCP1201 - PWM Current-Mode Controller

Description

Pin No.

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 internal structure, operating at a fixed 60 or 100 kHz, the controller supplies itself from the high--voltage rail, avoiding the need of an auxiliary winding. This feature naturally eases the designer’s.

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