XL7015E1

XLSEMI · DC-DC Converters · TO-252-5

XL7015E1 from XLSEMI, in a TO-252-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VIN power_in Power supply input pin, 5V to 80V operating range (100V absolute max). Requires an electrolytic bypass capacitor (e.g. 33uF/100V) between VIN and GND to suppress noise.
2 SW output Power switch output pin; switching node connected to the internal high-voltage NPN power transistor. Connects to the external inductor and freewheeling diode of the buck converter.
3 GND power_in Ground pin. The exposed metal tab of the TO252-5L package is also GND and should be tied to the ground plane for thermal dissipation.
4 FB input Feedback input pin. Senses the output voltage via an external resistor divider; internal reference is 1.25V. VOUT = 1.25 * (1 + R2/R1). Absolute max voltage -0.3V to 7V.
5 EN input Enable pin, active-low logic: LOW (<0.8V) enables the converter, HIGH (>1.6V) shuts it down. Floating is treated as low (enabled). Absolute max voltage -0.3V to 7V.
TAB GND power_in Exposed metal tab on the back of the TO252-5L package, electrically connected to GND. Used for thermal dissipation; solder to the PCB ground plane.
