RT9293BGJ6 from Richtek Tech, 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	Switching pin. Drain of the internal N-MOSFET switch; connects to the boost inductor and Schottky diode anode. Rated -0.3V to 50V absolute maximum.
2	GND	power_in	Ground pin. Return for both the power switch and control circuitry.
3	FB	input	Feedback pin. Connect the LED string return through a sense resistor R_SET to GND; the loop regulates FB to V_REF (300mV typ for RT9293B) to set the LED current.
4	EN	input	Chip enable (active high). Logic-high (V_IH >= 1.4V) turns the converter on; logic-low (V_IL <= 0.5V) shuts it down. Rated -0.3V to 6V.
5	VOUT	power_out	Output voltage sense pin. Connects to the boost output rail for OVP monitoring. Rated -0.3V to 46V; OVP threshold 46V (RT9293A/B default 50V) or 17.5V (RT9293B-20 option).
6	VIN	power_in	Input supply pin. Operating range 2.5V to 5.5V (abs max 6V). Bypass with a 2.2uF ceramic capacitor to GND.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`rt9293bgj6.step`	97 KB	You want the bare part, or you mark your own boards.
`rt9293bgj6-etched.step`	2.4 MB	You want the part with `RT9293BGJ6` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 555 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.
