XL9025

XLSEMI · DC-DC Converters · TO-263-5L

XL9025 from XLSEMI, in a TO-263-5L. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 GND power_in Ground pin.
2 FB input Feedback pin that senses the output voltage through an external resistor divider, with a 1.25V reference voltage.
3 SW output Power switch output pin; the switching node of the output power stage.
4 VC passive Internal voltage regulator bypass capacitor pin; a 1uF capacitor must be connected between VIN and VC.
5 VIN power_in Power input pin supporting a 5V to 40V DC operating range; an electrolytic capacitor must be placed in parallel between VIN and GND to suppress noise.
6 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).

CAD (KiCad official)

  • Symbol: XL9025
  • Footprint: Package_TO_SOT_SMD:TO-263-5_TabPin6
  • 3D model: TO-263-5L (KiCad packages3D, STEP)
  • 3D model files: xl9025-etched.step / xl9025-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); xl9025.step / xl9025.glb are the bare package body.
