XL2576HVS-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 | Supply input for the wide 4.5V to 50V operating range, and an electrolytic capacitor must be connected in parallel between VIN and GND to suppress noise. |
| 2 | SW | output | Power switch output pin; it is the switch node that carries the output power and switches between VIN and ground. |
| 3 | GND | power_in | Ground pin for the device. |
| 4 | FB | input | Feedback pin that senses the output voltage through an external resistor divider to regulate it; the reference voltage for the adjustable version is 1.23V. |
| 5 | EN | input | Enable pin, active low: a high level shuts the device down and it is low when left floating. |
| 6 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
