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.

Maximum rating
Stressing the device above the rating listed in the “Absolute Maximum Ratings” table may
cause permanent damage to the device. These are stress ratings only and operation of the
device at these or any other conditions above those indicated in the Operating sections of
this specification is not implied. Exposure to Absolute Maximum Rating conditions for
extended periods may affect device reliability. Refer also to the STMicroelectronics SURE
Program and other relevant quality documents.

Note: 1 This parameter applies when the start-up current source is OFF. This is the case when the
VDD voltage has reached VDDon and remains above VDDoff.
2 This parameter applies when the start up current source is on. This is the case when the
VDD voltage has not yet reached VDDon or has fallen below VDDoff.

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