XL2596HVP-12E1 from XLSEMI, in a SOP-8-EP. 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 input pin with a 4.5V to 50V operating range, which needs an electrolytic capacitor in parallel between VIN and GND to remove noise. |
| 2 | SW | output | Power switch output pin and the switching node that delivers output power. |
| 3 | FB | input | Feedback pin that senses the output voltage through an external resistor divider; the reference voltage is 1.23V on the adjustable version. |
| 4 | EN | input | Enable pin that is active low, with high level shutting the device down and the pin reading low when left floating. |
| 5 | GND | power_in | Ground pin. |
| 6 | GND | power_in | Ground pin. |
| 7 | GND | power_in | Ground pin. |
| 8 | GND | power_in | Ground pin. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
