XL1507-5.0E1

XLSEMI · DC-DC Converters · TO-252-5

XL1507-5.0E1 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 VIN power_in Supply Voltage Input Pin. Operates from a 4.5V to 40V DC voltage (absolute max 45V). Bypass VIN to GND with a suitably large capacitor to eliminate noise on the input.
2 OUTPUT output Power Switch Output Pin (SW). Output is the internal power transistor switch node that supplies power to the output through the external inductor and Schottky freewheeling diode. Rated for 3A continuous.
3 GND power_in Ground Pin. Care must be taken in layout: this pin should be placed outside of the Schottky diode to output capacitor ground path to prevent switching current spikes from inducing voltage noise into the XL1507. The exposed metal tab is also tied to GND.
4 FEEDBACK input Feedback Pin (FB). Senses the output voltage via an external resistor divider and regulates it. Internal feedback threshold voltage is 1.23V. On the -5.0 fixed version an internal divider (R1=2.5k, R2=7.6k) sets the 5V output.
5 ON/OFF input Enable Pin. Drive ON/OFF pin LOW to turn on the device; drive it HIGH to turn it off. TTL-compatible with hysteresis. Floating defaults low (device ON). Absolute max voltage is VIN.

CAD (KiCad official)

  • Symbol: XL1507-5.0E1
  • Footprint: Package_TO_SOT_SMD:TO-252-5_TabPin6
  • 3D model: TO-252-5 (KiCad packages3D, STEP)
  • 3D model files: xl1507-5-0e1-etched.step / xl1507-5-0e1-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); xl1507-5-0e1.step / xl1507-5-0e1.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
xl1507-5-0e1.step 196 KB You want the bare part, or you mark your own boards.
xl1507-5-0e1-etched.step 1.9 MB You want the part with XL1507-5.0E1 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 508 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.
