XLSEMI · DC-DC Converters · TO-263-5
XL7035E1 from XLSEMI, in a TO-263-5. 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 supporting a DC 10V to 80V input range; an electrolytic capacitor must be connected in parallel between VIN and GND to filter noise. |
| 2 | SW | output | Power switch output and the switching node that delivers output power. |
| 3 | GND | power_in | Ground pin. |
| 4 | FB | input | Feedback pin that senses the output voltage through an external resistor divider; the reference voltage is 1.25V. |
| 5 | OGND | power_in | Output ground pin. |
| 6 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
