    MOSFET on the same silicon chip. Typical applications cover off line power supplies for battery charger adapters, standby power supplies for TV or monitors, auxiliary supplies for motor control, etc. The internal control circuit offers the following benefits:

    Large input voltage range on the VDD pin accommodates changes in auxiliary supply

    voltage. This feature is well adapted to battery charger adapter configurations.

    • Automatic burst mode in low load condition.
    • Overvoltage protection in hiccup mode.
    • PIN FUNCTION

      NameFunction

      VDD

      Power supply of the control circuits. Also provides a charging current during start up thanks to a high voltage current source connected to the drain. For this purpose, an hysteresis comparator monitors the VDD voltage and provides two thresholds:

      - VDDon: Voltage value (typically 14.5V) at which the device starts switching and turns off the start up current source.

      - VDDoff: Voltage value (typically 8V) at which the device stops switching and turns on the start up current source.

      SOURCEPower MOSFET source and circuit ground reference.
      DRAINPower MOSFET drain. Also used by the internal high voltage current source during start up phase for charging the external VDD capacitor.

      FB

      Feedback input. The useful voltage range extends from 0V to 1V, and defines the peak drain MOSFET current. The current limitation, which corresponds to the maximum drain current, is obtained for a FB pin shorted to the SOURCE pin.
