XL4015E1 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. Layout-sensitive: should be placed outside of the Schottky-diode-to-output-capacitor ground path to prevent switching current spikes from inducing voltage noise into the device. |
| 2 | FB | input | Feedback pin. Senses the output voltage through an external resistor divider and regulates it against the internal 1.25V reference. Output voltage set by VOUT = 1.25 * (1 + R2/R1). |
| 3 | SW | power_out | Power switch output pin. Switch node connected to the drain of the internal power PMOS; supplies the switching waveform to the external inductor and freewheeling Schottky diode. Absolute max -0.3V to VIN. The TO263-5L metal tab is also electrically SW. |
| 4 | VC | passive | Internal voltage regulator bypass capacitor pin. Connect a 1 uF (105) ceramic capacitor from VC to VIN to bypass the internal regulator. |
| 5 | VIN | power_in | Supply voltage input pin. Operates from 8V to 36V DC (absolute max 40V). Bypass VIN to GND with a suitably large capacitor (e.g. 220 uF/50V) to eliminate input noise. |
