xl6019e1.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 -> 6 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

XL6019E1

XLSEMI · DC-DC Converters · TO-263-5

XL6019E1 from XLSEMI, in a TO-263-5. 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. Common return for input, output and internal circuitry.
2 EN input Enable pin. TTL-compatible: logic low shuts the converter down, logic high enables operation. Threshold typ. 1.4V (high) / 0.8V (low). Floating is treated as high. VEN range -0.3V to VIN.
3 SW output Power switch output. Drain of the internal N-channel power MOSFET; connect to the inductor/diode boost node. Absolute max VSW = 60V, internal SW overvoltage clamp typ. 60V. Also brought out on the metal tab.
4 VIN power_in Power supply input, 5V to 40V DC. Requires a bulk electrolytic capacitor between VIN and GND to suppress noise. Absolute max 45V.
5 FB input Output-voltage feedback sense pin. Internal reference is 1.25V; set VOUT with a resistor divider using VOUT = 1.25 × (1 + R2/R1).

CAD (KiCad official)

  • Symbol: XL6019E1
  • Footprint: Package_TO_SOT_SMD:TO-263-5_TabPin6
  • 3D model: TO-263-5 (KiCad packages3D, STEP)
  • 3D model files: xl6019e1-etched.step / xl6019e1-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); xl6019e1.step / xl6019e1.glb are the bare package body.

Provenance

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