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 V

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 V
Feedback input. The useful voltage range extends from 0 V to 1 V, 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.
