AL8806
HIGH EFFICIENCY 36V 1.5A BUCK LED DRIVER
Description
The AL8806 is a step-down DC/DC converter designed to drive LEDs
with a constant current. The device can drive up to 8 LEDs,
Pin Assignments
depending on the forward voltage of the LEDs, in series from a
voltage source of 6V to 36V. The AL8806 switches at frequencies up
to 1MHz. This allows the use of small size external components,
hence minimizing the PCB area needed.

Maximum output current of AL8806 is set via an external resistor
connected between the V IN and SET input pins. Dimming is achieved
by applying either a DC voltage or a PWM signal at the CTRL input
pin. An input voltage of 0.4V or lower at CTRL switches off the output
MOSFET simplifying PWM dimming.
