XL4016E1 from XLSEMI, in a TO-220-5. 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 reference pin for the device (0V return). |
| 2 | FB | input | Feedback input for output voltage regulation. An external resistor divider from VOUT sets the output; internal reference is 1.25V. VOUT = 1.25 * (1 + R2/R1). Absolute max 7V. |
| 3 | SW | output | Power switch output node (drain of internal PMOS). Connects to the external inductor and freewheeling Schottky diode. Also connected internally to the exposed metal tab. Peak switch current up to 12A (14A typ limit). |
| 4 | VC | passive | Internal voltage regulator bypass pin. Connect a 1uF ceramic capacitor between VIN and VC. |
| 5 | VIN | power_in | Power supply input, DC 8V to 36V recommended operating range (40V absolute max). Requires a bulk electrolytic capacitor to GND (e.g. 470uF/50V) to reduce input noise. |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 178 faces against 69 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.
