XLSEMI · DC-DC Converters · TO-263-5L
XL9713 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 | GND | power_in | Ground pin. |
| 2 | FB | input | Feedback pin that senses the output voltage through an external resistor divider, with a 1.25V reference voltage (VOUT=1.25*(1+R2/R1)). |
| 3 | SW | output | Power switch output pin and the switching node of the output power stage. |
| 4 | VC | passive | Internal voltage regulator bypass capacitor pin; a 1uF capacitor must be connected between VIN and VC. |
| 5 | VIN | power_in | Power supply input pin supporting 5V to 72V DC; an electrolytic capacitor must be connected in parallel between VIN and GND to suppress noise. |
| 6 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
