BL8032GCB6TR from BL(Shanghai Belling), in a SOT23-6. 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	Ground reference pin for the device.
2	SW	output	Switching pin that drives the inductor; the datasheet limits the switch node voltage VSW to -0.3V to (VIN+0.3V) absolute maximum.
3	VIN	power_in	Power supply input; the recommended input voltage range is 4.5V to 18V, with an absolute maximum of -0.3V to 19V.
4	FB	input	Adjustable-version feedback input that connects to the center point of the external resistor divider; the regulated feedback voltage is 0.8V typical (0.784V to 0.816V).
5	EN	input	Drive to logic-high (above 1.5V) to enable the IC and to logic-low (below 0.6V) to disable it into micropower shutdown; the absolute maximum on this pin is 19V.
6	BST	power_in	Supply input for the high-side FET gate drive circuit, which requires a 0.1μF capacitor connected between BST and SW; the boost voltage VBST-SW is limited to 5V absolute maximum.
