FP6291CLR-G1 from Advanced Analog Technology, in a SOT-23-6L. 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; connect to the boost inductor and the anode of the Schottky rectifier. Absolute maximum voltage 16V.
2	GND	power_in	IC Ground. Common return for the analog control circuitry and the power MOSFET source.
3	FB	input	Error Amplifier Inverting Input. Connect to a resistor divider from VOUT to set the output voltage; regulated to the internal 0.6V (±2%) reference.
4	EN	input	Enable Control (Active High). Drive above VEN(enable) ≈ 0.96V to enable the converter; below 0.6V places the device in shutdown (ICC ≈ 0.1µA). Do not leave floating.
5	VCC	power_in	IC Power Supply input. Operating range 2.6V to 5.5V (absolute maximum 6V). Bypass to GND with a local ceramic capacitor.
6	OC	input	Adjustable Current Limit. Connect a resistor (16kΩ to 96kΩ) from OC to GND to program the over-current threshold from 3A down to 0.5A.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`fp6291clr-g1.step`	97 KB	You want the bare part, or you mark your own boards.
`fp6291clr-g1-etched.step`	2.1 MB	You want the part with `FP6291CLR-G1` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 522 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.
