SCT2330TVBR from SCT, in a TSOT-23-6L. 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	FB	input	Buck converter output feedback sensing voltage. Connect a resistor divider from VOUT to FB to set the output voltage. The device regulates FB to the internal 0.8V (typ) reference (0.792V-0.808V).
2	EN	input	Enable logic input. Floating the pin enables the device. Supports high-voltage input up to VIN, so it can be tied directly to VIN for automatic enable. Precision enable thresholds 1.18V rising / 1.1V falling allow programmable UVLO threshold and hysteresis.
3	VIN	power_in	Power supply input, 3.8V to 32V operating range (40V absolute max). Must be locally bypassed with a ceramic capacitor close to the pin.
4	GND	power_in	Power ground. Must be soldered directly to the ground plane for proper thermal dissipation and low-impedance return path.
5	SW	output	Switching node of the buck converter. Connect the output inductor between SW and VOUT. Also forms the low reference for the BST bootstrap capacitor.
6	BST	power_in	Bootstrap supply for the high-side power MOSFET gate driver. Connect a 0.1µF or greater ceramic capacitor between BST and SW. Absolute max 40V referenced to GND.
