1200AP40 - NCP1200AP40

General Description

Pin No.

1 Pin Name Adj Function Adjust the skipping peak current Pin Description This pin lets you adjust the level at which the cycle skipping process takes place.

Shorting this pin to ground, permanently disables the skip cycle feature.

Key Features

  • an efficient protective circuitry which, in presence of an overcurrent condition, disables the output pulses while the device enters a safe burst mode, trying to restart. Once the default has gone, the device auto.
  • recovers. Features 8 1 http://onsemi. com.

ow Standby Power Housed in SOIC−8 or PDIP−8 package, the NCP1200A enhances the previous NCP1200 series by offering a reduced optocoupler current together with an increased drive capability. Due to its novel concept, the circuit allows the implementation of complete off−line AC−DC adapters, battery charger or a SMPS where standby power is a key parameter. With an internal structure operating at a fixed 40 kHz, 60 kHz 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 task in battery charger applications.
