AL8860MP-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	Current-set pin. Connect resistor Rs from this pin to VIN to define the nominal average output current: I_OUT_NOM = 0.1 / Rs. Mean current sense threshold V_SENSE is typically 100 mV (referenced to VIN). SET pin input current is typically 8 µA.
2	GND	power_in	Ground (0V). Device ground reference.
3	GND	power_in	Ground (0V). Device ground reference (second GND pin, tie to pin 2).
4	CTRL	input	Multi-function on/off and brightness control pin. Leave floating for normal operation. Drive below 0.2 V to disable output (V_EN(OFF) = 0.2 V falling). Drive with a DC voltage 0.3 V < CTRL < 2.5 V for analog dimming (0% to 100% of I_OUT_NOM). Drive with a PWM signal (from open-collector/open-drain) for PWM dimming with linear range 1% to 100% for f < 500 Hz. Connecting a capacitor to GND increases soft-start time (default ~0.1 ms, ~1.5 ms per 1 nF added). V_EN(ON) rising = 0.25 V typ.
5	SW	output	Drain of internal 40V NMOS power switch. Connect to inductor / freewheeling diode of the buck power stage. R_SW(on) is typically 0.2 Ω at 100 mA. Rated for -0.3 to +42 V.
6	SW	output	Drain of internal 40V NMOS power switch (second SW pin, tie to pin 5 for reduced impedance / current handling).
7	N/C	unconnected	No internal connection. Leave floating or tie to GND.
8	VIN	power_in	Input supply voltage, 4.5 V to 40 V operating range (absolute max +42 V). Decouple to GND with a 10 µF or higher X7R ceramic capacitor placed close to the device.
EP	EP	power_in	Exposed thermal pad. Connect to GND and to the PCB thermal mass for enhanced thermal impedance. Should NOT be used as the electrical ground conduction path (make electrical ground connections through pins 2 and 3).
