XLSEMI · DC-DC Converters · TO-252-5L
XL1507A-ADJE1 from XLSEMI, in a TO-252-5L. 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 | Power input pin supporting a DC 4.5V to 50V operating voltage range; an electrolytic capacitor must be connected in parallel between VIN and GND to remove noise. |
| 2 | SW | output | Power switch output pin; SW is the switch node that delivers the 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 for the adjustable version is 1.23V. |
| 5 | EN | input | Enable pin, active low: low level enables operation, high level shuts down, and the pin is low when left floating. |
