SCT9320STDR from SCT, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	BOOT	passive	Bootstrap supply for the high-side MOSFET gate driver. Connect a 0.1 µF (or greater) ceramic capacitor between BOOT and SW; the cap is refreshed when the low-side FET turns on.
2	VIN	power_in	Power supply input, 3.8 V to 32 V. Must be locally bypassed with a low-ESR ceramic capacitor placed close to the pin.
3	EN	input	Enable logic input. Floating the pin enables the device; can be tied directly to VIN (rated up to 34 V). Precision enable thresholds: 1.18 V rising / 1.1 V falling for programmable UVLO with hysteresis.
4	NC	unconnected	Not connected. Leave floating or tie to a copper island for thermal relief; no internal connection.
5	FB	input	Buck converter output feedback sensing input. Connect a resistor divider from VOUT to FB to set the output voltage; the internal reference regulates FB to 0.8 V typical (0.792 V-0.808 V).
6	NC	unconnected	Not connected. Leave floating or tie to a copper island for thermal relief; no internal connection.
7	GND	power_in	Power ground return for the low-side MOSFET and controller. Must be soldered directly to the ground plane with a low-impedance connection.
8	SW	power_out	Switching node of the buck converter. Connect to the output inductor and to the BOOT capacitor. High dV/dt node; keep trace short and shielded to minimize EMI.
