XL6008E1 from XLSEMI, in a TO-252-5. 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 pin. Return for the internal power MOSFET source and control circuitry.
2	EN	input	Enable pin. Drive EN low (<0.8V) to shut the device down; drive high (>1.4V) to enable. Floating defaults high. TTL-compatible shutdown input; input leakage ~3uA (typ), 10uA (max).
3	SW	output	Power switch output pin. Drain of the internal N-channel power MOSFET; connects to the inductor. Rated up to 60V with built-in over-voltage protection, 3A switch current limit, Rdson ~110 mohm typ.
4	VIN	power_in	Supply voltage input. Operates from 3.6V to 32V DC (absolute max 36V). Bypass VIN to GND with a suitably large capacitor (e.g. 47uF/50V) to eliminate input noise.
5	FB	input	Feedback pin. Feedback threshold voltage is 1.25V (typ, 1.213V to 1.287V). Output voltage set by external divider: VOUT = 1.25 * (1 + R2/R1).

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`xl6008e1.step`	196 KB	You want the bare part, or you mark your own boards.
`xl6008e1-etched.step`	1.9 MB	You want the part with `XL6008E1` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 496 faces against 139 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.
