AL8806

HIGH EFFICIENCY 30V 1.5A BUCK LED DRIVER

Description

Pin Assignments

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, depending on the forward voltage of the LEDs, in

series from a voltage source of 6V to 30V. The AL8806

switches at frequency 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_INand 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.
