TPS563201DDCR from Texas Instruments, in a SOT-23-THIN-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	GND	power_in	Ground pin. Source terminal of the low-side power NFET and ground return for the controller circuit. Sensitive VFB return should tie to this GND at a single point.
2	SW	output	Switch node connection between the high-side NFET and the low-side NFET. Connects to the output inductor. Absolute max −2 V to 19 V.
3	VIN	power_in	Input voltage supply pin (4.5 V to 17 V). Drain terminal of the integrated high-side power NFET; requires local input decoupling capacitance.
4	VFB	input	Converter feedback input. Connect to the output through an external resistor divider that sets the output voltage; internal reference is ~0.768 V (0.749-0.787 V).
5	EN	input	Enable input control. Active high; pull above 1.6 V to enable, below 0.8 V to disable. Internal ~400 kΩ pull-down to GND; do not leave floating.
6	VBST	power_out	Bootstrap supply for the high-side NFET gate driver. Connect a 0.1 µF ceramic capacitor between VBST and SW.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`tps563201ddcr.step`	97 KB	You want the bare part, or you mark your own boards.
`tps563201ddcr-etched.step`	2.7 MB	You want the part with `TPS563201DDCR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 638 faces against 117 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
