FP6291LR-G12 from Advanced Analog Technology FP6291LR G1, 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	output	Power switch output. Drain of the internal 0.2Ω, 16V N-channel power MOSFET; connects to the boost inductor and Schottky rectifier. Absolute maximum LX voltage is 16V.
2	GND	power_in	IC ground. Reference for all internal circuitry and source of the internal power MOSFET.
3	FB	input	Error amplifier inverting input. Connect a resistor divider from VOUT to set the output voltage; regulates to the internal 0.6V (±2%) precision reference.
4	EN	input	Enable control, active high. VEN ≥ 0.96V enables the converter; VEN ≤ 0.6V shuts it down (shutdown current 0.1µA typ). Absolute maximum 6V. Do not leave floating.
5	VCC	power_in	IC power supply input. Operating range 2.6V to 5.5V; absolute maximum 6V. Bypass locally with a ceramic capacitor. UVLO threshold ≈ 2.2V with 0.1V hysteresis.
6	OC	input	Adjustable current limit. Connect an external resistor (19kΩ to 96kΩ) from OC to GND to program the peak switch current limit from ≈2.5A down to ≈0.5A. With 75kΩ, IOCP is 0.53-0.67A on the FP6291LR-G12 variant.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`fp6291lr-g12.step`	97 KB	You want the bare part, or you mark your own boards.
`fp6291lr-g12-etched.step`	2.1 MB	You want the part with `FP6291LR-G12` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 523 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.
