XL4013E1

XLSEMI · DC-DC Converters · TO-252-5

XL4013E1 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 GND power_in Ground pin. Care must be taken in layout: this pin should be placed outside of the Schottky diode-to-output-capacitor ground path to prevent switching current spikes from inducing voltage noise into the XL4013.
2 FB input Feedback pin. Through an external resistor divider network, FB senses the output voltage and regulates it. The feedback threshold voltage is 1.25 V (VOUT = 1.25 * (1 + R2/R1)).
3 SW power_out Power switch output pin. SW is the switch node that supplies power to the output through the external inductor and Schottky catch diode. The metal tab of the TO252-5L is also connected to SW.
4 VC passive Internal voltage regulator bypass capacitor pin. Connect a 1 uF capacitor from VC to VIN to bypass the internal 3.3 V regulator.
5 VIN power_in Supply voltage input pin. XL4013 operates from an 8 V to 36 V DC input (absolute max 40 V). Bypass VIN to GND with a suitably large capacitor (e.g. 100 uF/50 V) to eliminate noise on the input.
