TPS54308DDCR from Texas Instruments, 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 | GND | power_in | Ground pin. Source terminal of the low-side power NFET and the ground return for the controller circuit. Connect 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. Connects to the external inductor. Absolute max -0.3 V to 30 V (steady state). |
| 3 | VIN | power_in | Input voltage supply pin (4.5 V to 28 V recommended). Drain terminal of the high-side power NFET. Bypass to GND with a local ceramic capacitor. |
| 4 | FB | input | Converter feedback input. Connect to the regulated output voltage through a resistor divider; internal reference is 0.596 V (typ). |
| 5 | EN | input | Enable pin. Float to enable the converter (internal pull-up). Drive low (below ~1.1 V) to shut down. Enable rising threshold 1.21 V typ; absolute max 7 V. |
| 6 | BOOT | power_out | Supply for the high-side NFET gate drive. Connect a 0.1-µF bootstrap capacitor between BOOT and SW. Absolute max BOOT-SW = 7 V. |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 616 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.
