SX1308 from Suosemi, in a SOT-23-6. Pinout and pin descriptions extracted from the datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	SW	output	Power Switch Output. Drain of the internal power MOSFET switch. Connect the boost inductor and output rectifier (Schottky) diode to this pin. SW can swing between GND and 28V; peak SW current rating 4A.
2	GND	power_in	Ground pin. Should be connected to a strong ground plane for heat sinking and noise protection.
3	FB	input	Feedback Input. Internal reference is 0.6V (typ, 0.588-0.612V). Connect a resistor divider from VOUT to FB to set the output voltage: VOUT = 0.6V × (1 + R1/R2). Input bias current is typically −10nA.
4	EN	input	Regulator On/Off Control Input. VIH = 1.5V min, VIL = 0.4V max. A high input turns on the converter; a low input shuts it down (IQ = 0.1µA typ). Tie to VIN for automatic startup. Absolute max -0.3V to 26V.
5	IN	power_in	Input supply pin. Operating range 2V to 24V (absolute max 26V). Must be locally bypassed with a low-ESR ceramic capacitor (22µF X5R/X7R recommended) placed close to the IC.
6	NC	unconnected	No Connect. Not internally bonded; leave floating or tie to a non-noise-sensitive net.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`sx1308.step`	97 KB	You want the bare part, or you mark your own boards.
`sx1308-etched.step`	1.7 MB	You want the part with `SX1308` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 394 faces against 117 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.
