AP3032KTR-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	SW	output	Switch pin. Drain of the internal power NPN/NMOS switch; connect the external boost inductor and Schottky diode here. Absolute max VSW = 38V.
2	GND	power_in	Device ground return for the internal power switch and control circuitry.
3	FB	input	Voltage feedback input to the error amplifier. Regulates to VFB = 200mV (typ, 188-212mV). Typically tied to the top of a current-sense resistor at the bottom of the LED string. Absolute max = 20V.
4	CTRL	input	Enable and dimming control pin. Drive high to enable the IC, low to disable. Accepts a PWM input for LED dimming; when the logic-low interval is less than ~0.7 ms the part enters standby (power switch off, soft-start preserved) to achieve high-frequency PWM dimming. VCTRL threshold ~1.2V, bias current ~60 uA, absolute max 20V.
5	OV	input	Over-voltage protection sense input. Connect directly to the boost output. When the output reaches VOVP ~27V the output is clamped to protect the IC under open-load conditions. Absolute max 35V.
6	VIN	power_in	Input supply pin, 2.7V to 9V operating (20V absolute max). Must be locally bypassed with a ceramic capacitor. Quiescent current ~4 mA (typ), shutdown current ~50 uA when CTRL = 0V.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`ap3032ktr-g1.step`	97 KB	You want the bare part, or you mark your own boards.
`ap3032ktr-g1-etched.step`	2.3 MB	You want the part with `AP3032KTR-G1` 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.
