XL4001E1 from XLSEMI, in a SOIC-8. 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 | SW | output | Power switch output node that supplies power to the output; internal switch rated for 2A load current. |
| 2 | SW | output | Power switch output node that supplies power to the output; internal switch rated for 2A load current. |
| 3 | GND | power_in | Ground pin; connected to back exposed pad; serves as high-current return path. |
| 4 | FB | input | Feedback pin; external resistor divider network senses output voltage and regulates it; feedback threshold voltage is 1.235V. |
| 5 | CS | input | Output current sense pin for constant-current loop; load current Iload = 0.155V/Rcs. |
| 6 | EN | input | Enable pin; drive low to turn on device, drive high to turn off; floating defaults to low (enabled). |
| 7 | VIN | power_in | Supply voltage input pin; XL4001 operates from 4.5V to 40V DC; bypass to GND with large capacitor to eliminate noise. |
| 8 | VIN | power_in | Supply voltage input pin; XL4001 operates from 4.5V to 40V DC; bypass to GND with large capacitor to eliminate noise. |
