xl4016e1.lbr rebuild the library on adom-lbr 2.32.0. The published copy was built by 2.18.0, which imported every KiCad roundrect and oval pad as a SQUARE EAGLE smd; this carries the real pad shape across (0 -> 0 rounded pads) and stops dropping geometry drawn on KiCad User.N layers. Attributes, connects, pads and the pin-1 marker are gated against decreasing and are unchanged. · Ray 1mo ago

XL4016E1

XLSEMI · DC-DC Converters · TO-220-5

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.

  • XL4016E1

CAD (KiCad official)

  • Symbol: XL4016E1
  • Footprint: Package_TO_SOT_THT:TO-220-3_Vertical
  • 3D model: TO-220-5 (KiCad packages3D, STEP)
  • 3D model files: xl4016e1-etched.step / xl4016e1-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); xl4016e1.step / xl4016e1.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
xl4016e1.step 104 KB You want the bare part, or you mark your own boards.
xl4016e1-etched.step 617 KB You want the part with XL4016E1 already on it.

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.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: XLSEMI datasheet (10 pp, sha256 af9fe1b7a2838fe9, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
