XLSEMI · LED Drivers · TO-263-5L
XL9505 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, the return reference for the device. |
| 2 | CS | input | Output current sense pin with a 0.23V CS reference voltage, and the absolute maximum CS voltage is -0.3 to 7 V. |
| 3 | SW | output | Power switch output pin that forms the switching node of the output power stage, with absolute maximum VSW of -0.3 to VIN V. |
| 4 | VC | power_out | Internal voltage regulator bypass pin that requires a 1uF capacitor between VIN and VC, with absolute maximum VC of -0.3 to VIN V. |
| 5 | VIN | power_in | Supply input pin for the 5V to 45V operating range, which requires a parallel capacitor between VIN and GND to suppress noise, with absolute maximum VIN of -0.3 to 50 V. |
| 6 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
