XL2596HVS-12E1 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 | VIN | power_in | Power supply input supporting a DC 4.5V~50V wide operating range, requiring an electrolytic capacitor between VIN and GND to eliminate noise. |
| 2 | SW | output | Power switch output pin, the switching node of the output power stage. |
| 3 | GND | power_in | Ground pin. |
| 4 | FB | input | Feedback pin that senses the output voltage for regulation (via external resistor divider on the ADJ version, reference voltage 1.23V). |
| 5 | EN | input | Enable pin, active low to operate and high to shut down, reads as low when floating (VEN_H 1.4V shutdown, VEN_L 0.8V on). |
| 6 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
