SY7208ABC from Silergy Corp, 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	LX	power_out	Inductor switching node. Connect an inductor between IN pin and LX pin. Integrated N-MOSFET drain; drives the boost inductor. Absolute max 26V; dynamic 50ns rating IN+3V to GND-4V.
2	GND	power_in	Ground pin. Reference for internal circuitry and source of internal N-MOSFET.
3	FB	input	Feedback pin. Connect a resistor R1 between VOUT and FB, and a resistor R2 between FB and GND to program the output voltage: VOUT = 0.6V * (R1/R2 + 1). Internal reference VREF = 0.6V (typ).
4	EN	input	Enable control input. Drive high (VENH >= 2V) to turn on the part; low (VENL <= 0.4V) to shut down (~1uA). Do not leave floating. Absolute max 26V.
5	IN	power_in	Power input pin. Bias/supply input, 3V to 25V operating range (26V abs max). Bypass with a local ceramic capacitor to GND.
6	NC	unconnected	No connection. Leave floating or tie to GND per PCB preference.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`sy7208abc.step`	97 KB	You want the bare part, or you mark your own boards.
`sy7208abc-etched.step`	2.0 MB	You want the part with `SY7208ABC` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 474 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.
