AP3036BKTR-G1 from Diodes Incorporated, 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	CTRL	input	Shutdown and dimming pin. Drive to >=1.5V to enable the device; drive to <=0.4V to disable. Accepts a PWM signal (tested at 0.5kHz and 100kHz) for LED brightness dimming. CTRL bias current is typically 100µA; absolute max 20V, recommended max 16V.
2	VOUT	power_out	Boost converter output pin. Connects to the cathode of the integrated Schottky diode; the LED string anode ties here. Output overvoltage protection clamps this node at ~30V typical if the LED string opens.
3	VIN	power_in	Input supply pin. Recommended operating range 2.5V to 16V (absolute max 20V). Must be decoupled with a local bypass capacitor (typ. 1µF X5R/X7R).
4	SW	output	Switch pin, collector of the internal NPN power switch. Connects to the external boost inductor (typ. 22µH). Absolute maximum 38V; switch current limit ~550mA at 40%/80% duty cycle.
5	GND	power_in	Device ground return.
6	FB	input	Voltage feedback pin for LED current regulation. Internal reference is 200mV; the single external sense resistor from the bottom of the LED string to GND sets LED current as I_LED = 0.2V / R_FB. FB bias current is typically 35nA (max 100nA); absolute max 20V.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`ap3036bktr-g1.step`	97 KB	You want the bare part, or you mark your own boards.
`ap3036bktr-g1-etched.step`	2.6 MB	You want the part with `AP3036BKTR-G1` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 620 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.
