AL8807QMP-13 from Diodes Incorporated, in a MSOP-8-EP. 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	SET	input	Set Nominal Output Current pin. An external resistor (RS) from VIN to SET programs the nominal LED current as I_OUTnom = 0.1 / RS (V_TH ≈ 100 mV, ISET typ 16 µA).
2	GND	power_in	Ground pin. Dominant heat conduction path from the die is through this pin; use a large ground plane with thermal vias.
3	GND	power_in	Ground pin. Tie together with pin 2 to the system ground plane.
4	CTRL	input	Dimming and On/Off Control input. Leave floating (internal ~50 kΩ to V_REF = 2.5V) for 100% output. Drive <0.4V to shut off the output MOSFET; 0.5V-2.5V DC scales output current from 20% to 100%; a PWM signal (low ≤0.4V, high ≥2.6V, transitions <1 µs) provides PWM dimming below the SET-programmed level. Absolute max 6V.
5	SW	output	Switch pin - drain of the internal power MOSFET. Connect the inductor and freewheeling Schottky diode here; keep track length short to reduce EMI. R_DS(on) typ 0.25 Ω, absolute max V_SW = 40V.
6	SW	output	Switch pin - tied internally to pin 5; parallel both to share switch current up to 1.3A (2.5A peak).
7	N/C	unconnected	No internal connection. Leave floating or tie to GND.
8	VIN	power_in	Input supply pin, 6V to 30V (absolute max 40V). Must be locally decoupled to GND with ≥2.2 µF X7R ceramic capacitor placed close to the pin.
EP	EP	passive	Exposed pad / thermal tab on the bottom of the MSOP-8EP package. Solder to the GND copper pour and thermal mass to lower θJA (typ 69 °C/W). Not a primary electrical ground conduction path.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`al8807qmp-13.step`	194 KB	You want the bare part, or you mark your own boards.
`al8807qmp-13-etched.step`	2.1 MB	You want the part with `AL8807QMP-13` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 522 faces against 63 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.
