TPS61165DBVR from Texas Instruments, 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	Input supply pin for the IC. Connect VIN to a supply voltage between 3 V and 18 V. Absolute maximum rating is 20 V.
2	CTRL	input	Control pin of the boost converter. Multifunctional pin used for enable control, PWM brightness control, and EasyScale one-wire digital dimming. Logic high >=1.2 V; logic low <=0.4 V; internal pull-down 400-1600 kOhm.
3	SW	input	Switching node of the internal N-channel MOSFET (Rds(on) ~0.3 Ohm, 1.2-A current limit). Connect the switched side of the boost inductor to SW. Also used to sense the output voltage for open-LED protection (Vovp = 38 V typical). Absolute maximum 40 V.
4	GND	power_in	Device ground. Return path for input and switching currents; connect to the analog ground plane.
5	COMP	output	Output of the transconductance error amplifier (Gea = 320 umho typ). Connect an external compensation capacitor (typ 220 nF) from COMP to GND to compensate the current-mode boost loop.
6	FB	input	Current-feedback pin. Connect the LED current-sense resistor Rset from FB to GND; the loop regulates FB to Vref = 200 mV (2% accuracy) for full-brightness, and to 20-50 mV under PWM/EasyScale brightness control. Input bias <=2 uA.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`tps61165dbvr.step`	97 KB	You want the bare part, or you mark your own boards.
`tps61165dbvr-etched.step`	2.3 MB	You want the part with `TPS61165DBVR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 558 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.
