FL7760BM6X from onsemi, 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	VIN	power_in	IC input pin. Connect to the high voltage input line (up to 70 V) to supply current to the IC's internal regulator.
2	GND	power_in	Ground reference of the IC.
3	DIM	input	Analog/PWM/Hybrid dimming input. DIM voltage determines the LED current regulation reference and switching is terminated when DIM = 0 V. Effective dimming range approximately 0.45 V to 3.0 V; if dimming is not used, add a 0.1 uF bypass capacitor between DIM and GND.
4	DRV	output	Gate driver output. Connect to the external MOSFET gate. Peak pull-up current 1.5 A, peak pull-down current 2.5 A; gate-high voltage typ 5 V.
5	VCC	power_out	IC supply pin, regulated internally from VIN (typ 5 V). Bypass to GND with a ceramic capacitor. IC start threshold ~4.5 V, stop threshold ~3.5 V.
6	SEN	input	Current sense input. Connect to the external high-side sense resistor to set the output LED current regulation. Internal reference voltage typ 200 mV.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`fl7760bm6x.step`	97 KB	You want the bare part, or you mark your own boards.
`fl7760bm6x-etched.step`	1.8 MB	You want the part with `FL7760BM6X` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 442 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.
