VIPER06HS from STMicroelectronics, in a SOP-10. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	GND	power_in	Connected to the source of the internal power MOSFET and the controller ground reference.
2	VDD	power_in	Supply voltage of the control section that provides the charging current of the external capacitor, with an operating voltage range of 11.5 V to 23.5 V and an input current limit of 20 mA.
3	LIM	input	Sets the drain current limitation, which is reduced by an external resistor to GND and is left open for the default limit, with an input pin voltage range of -0.3 V to 2.8 V.
4	FB	input	Inverting input of the internal transconductance error amplifier with a reference voltage VREF_FB of 3.2 V to 3.4 V, with an input pin voltage range of -0.3 V to 4.8 V.
5	COMP	output	Output of the internal transconductance error amplifier used for loop compensation, with a linear voltage range from VCOMPL to VCOMPH and an input pin voltage range of -0.3 V to 3.5 V.
6	DRAIN	passive	High-voltage drain pin of the internal power MOSFET, rated 800 V, which also draws the high-voltage startup bias current and is connected to the metal frame to help heat dissipation.
7	DRAIN	passive	High-voltage drain pin of the internal power MOSFET, rated 800 V, which also draws the high-voltage startup bias current and is connected to the metal frame to help heat dissipation.
8	DRAIN	passive	High-voltage drain pin of the internal power MOSFET, rated 800 V, which also draws the high-voltage startup bias current and is connected to the metal frame to help heat dissipation.
9	DRAIN	passive	High-voltage drain pin of the internal power MOSFET, rated 800 V, which also draws the high-voltage startup bias current and is connected to the metal frame to help heat dissipation.
10	DRAIN	passive	High-voltage drain pin of the internal power MOSFET, rated 800 V, which also draws the high-voltage startup bias current and is connected to the metal frame to help heat dissipation.
