SM8102ABC from Silergy Corp, in a SOT-23-6. 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	BS	passive	Boot-strap pin. Supplies the high-side gate driver. Connect a 0.1µF (100nF) ceramic capacitor between BS and LX. BS-LX voltage rated -0.3V to 4V.
2	GND	power_in	Power ground pin. Return for input decoupling and internal low-side MOSFET.
3	FB	input	Output feedback pin. Connect to the center point of the external output resistor divider to program the output voltage: VOUT = 0.6 × (1 + RH/RL). Internal reference VREF = 600mV (588-612mV). FB input current ±50nA max.
4	EN	input	Enable control input. Pull high to turn the converter on; do not leave floating. Rising threshold typ 1.2V (1.08-1.32V), falling threshold typ 1.0V (0.9-1.1V). Rated -0.3V to VIN+0.3V.
5	IN	power_in	Input supply pin. 4.2V to 18V operating range (abs max 19V). Decouple to GND with at least a 10µF ceramic capacitor.
6	LX	power_out	Switching node / inductor pin. Connect to the external power inductor. Also forms the low reference for the bootstrap capacitor. Rated -0.3V to VIN+0.3V (dynamic IN+3V to GND-5V for 10ns).
