AP62200WU-7 from Diodes Incorporated, in a TSOT-26. 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	GND	power_in	Power ground. Reference for the IC and return path for the low-side MOSFET.
2	SW	power_out	Power switching output. Switching node that supplies power to the output; connect the output LC filter from SW to the output load. Absolute max -2.5V to VIN+2.0V (20ns).
3	VIN	power_in	Power input. Supplies power to the IC and step-down converter power MOSFETs. Drive with 4.2V to 18V; bypass VIN to GND with a suitably large capacitor (typ. 10µF) to eliminate switching noise.
4	FB	input	Feedback sensing terminal for the output voltage. Connect to the resistive divider from VOUT; regulated to 0.800V (AP62200/AP62201) or 0.763V (AP62200T).
5	EN	input	Enable input. Digital input that turns the regulator on (high) or off (low). Leave floating for automatic startup via UVLO. Precision threshold at 1.2V allows programming a custom UVLO with a resistor divider from VIN.
6	BST	passive	High-side gate drive boost input. Supplies the drive for the high-side N-channel MOSFET. Connect a 100nF bootstrap capacitor from BST to SW.
