AP5724WG-7 from Diodes Incorporated, in a SOT-26. 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. Connect the boost inductor and Schottky diode here. Internal NMOS power switch (Rds(on) ≈ 0.95Ω typ, 1.2Ω max) rated to 34V. Minimize trace area to reduce EMI.
2	GND	power_in	Device ground return.
3	FB	input	Feedback pin. Regulates to a 0.1V reference (0.09-0.11V). Connect the cathode of the lowest LED and the current-set resistor here; RSET = 0.1V / ILED.
4	EN	input	Converter On/Off control. VIH ≥ 1.5V turns the converter on; VIL ≤ 0.4V turns it off. Cannot be left floating; tie to VIN for automatic startup. Pin pull-low current ≈ 4µA (6µA max). PWM dimming input.
5	OVP	input	Output over-voltage detect input. Trips at 30V typ (26V min / 34V max) to protect the switch and output stage from open-LED-string conditions. Rated to 35V absolute maximum.
6	VIN	power_in	Input supply pin. Operating range 2.7V-5.5V (7V absolute max). Bypass locally with a 1µF or 2.2µF ceramic capacitor to reduce input noise. UVLO ≈ 2.2V typ.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`ap5724wg-7.step`	97 KB	You want the bare part, or you mark your own boards.
`ap5724wg-7-etched.step`	1.6 MB	You want the part with `AP5724WG-7` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 408 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.
