Pinout and package

Pin	Name	Function	Source
1		SOURCE: Power MOSFET source and circuit ground reference
2		SOURCE: Power MOSFET source and circuit ground reference
3		FB: 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.
4		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 (typically 14.5 V) at which the device is
5		DRAIN: Power MOSFET drain. Also used by the internal high voltage current source during start up phase for charging the external VDD capacitor.
6		DRAIN: Power MOSFET drain. Also used by the internal high voltage current source during start up phase for charging the external VDD capacitor.
7		DRAIN: Power MOSFET drain. Also used by the internal high voltage current source during start up phase for charging the external VDD capacitor.
8		DRAIN: Power MOSFET drain. Also used by the internal high voltage current source during start up phase for charging the external VDD capacitor.
