SGM3204YN6G from SGMICRO, in a SOT-23-6. 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	OUT	power_out	Negative power output with VOUT = -VIN. Bypass OUT to GND with the output filter capacitor COUT (typ 3.3µF). Delivers up to 200mA.
2	IN	power_in	Supply input. Connect to an input supply in the 1.4V to 5.5V range. Bypass IN to GND with a capacitor of the same value as the flying capacitor (typ 3.3µF).
3	CFLY-	passive	Negative terminal of the flying capacitor CFLY (typ 3.3µF). Connect between CFLY- and CFLY+ for the charge pump.
4	GND	power_in	Ground reference for the device.
5	EN	input	Enable control input. When EN is High (VINH ≥ 1.5V), the chip is in active mode. When EN is Low (VINL ≤ 0.4V), the chip is in shutdown mode (IQ typ 0.7µA).
6	CFLY+	passive	Positive terminal of the flying capacitor CFLY (typ 3.3µF). Connect between CFLY+ and CFLY- for the charge pump.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`sgm3204yn6g.step`	97 KB	You want the bare part, or you mark your own boards.
`sgm3204yn6g-etched.step`	2.3 MB	You want the part with `SGM3204YN6G` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 552 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.
