XL1410E1 from XLSEMI, in a SOIC-8. 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	NC	unconnected	No Connect. Not internally bonded; leave floating or tie to a nearby copper island for mechanical stability.
2	VIN	power_in	Supply Voltage Input Pin. Operates from 3.6V to 28V DC. Bypass VIN to GND with a suitably large capacitor (e.g. 220uF/35V) to eliminate input noise. Absolute max Vin = 32V.
3	SW	power_out	Power Switch Output Pin (SW). Internal high-side MOSFET switch node that drives the external inductor and Schottky catch diode. Absolute max Vsw range is -0.3V to Vin.
4	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 XL1410.
5	FB	input	Feedback Pin (FB). Through an external resistor divider network, FB senses the output voltage and regulates it. Feedback threshold voltage is 1.222V (typ), giving VOUT = 1.222 x (1 + R2/R1).
6	NC	unconnected	No Connect. Not internally bonded; leave floating.
7	EN	input	Enable Pin. Drive EN low to turn off the device, drive high to turn it on. Floating defaults high. Threshold ~1.4V (High/ON), 0.8V (Low/OFF); absolute max -0.3V to Vin.
8	NC	unconnected	No Connect. Not internally bonded; leave floating.

CAD (KiCad official)

3D model: SOIC-8 (KiCad packages3D, STEP)

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`xl1410e1.step`	122 KB	You want the bare part, or you mark your own boards.
`xl1410e1-etched.step`	1.3 MB	You want the part with `XL1410E1` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 362 faces against 147 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
