TPS563208DDCR from Texas Instruments, in a TSOT-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 | GND | power_in | Ground pin. Source terminal of the low-side power NFET and the ground return for the controller circuit. Connect the sensitive VFB to this GND at a single point. |
| 2 | SW | output | Switch node connection between the internal high-side NFET and low-side NFET. Connect to the output inductor. Absolute-max range −2 V to 19 V; SW voltage referenced during 10-ns transient extends −3.5 V to 21 V. |
| 3 | VIN | power_in | Input voltage supply pin and drain terminal of the high-side power NFET. Recommended operating range 4.5 V to 17 V. Bypass to GND with a low-ESR ceramic capacitor. |
| 4 | VFB | input | Converter feedback input. Connect to the output voltage through a feedback resistor divider. Internal reference V_FBTH ≈ 768 mV (CCM); input current ≤ ±0.1 µA. |
| 5 | EN | input | Enable input control. Active high; must be pulled up to enable the device. V_ENH ≥ 1.6 V (on), V_ENL ≤ 0.8 V (off). Internal pull-down resistance to GND ≈ 400 kΩ (225-900 kΩ). |
| 6 | VBST | power_out | Bootstrap supply input for the high-side NFET gate-drive circuit. Connect a 0.1-µF ceramic capacitor between VBST and SW. Absolute-max VBST (vs SW) 6.5 V. |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 682 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.
