AL8806 HIGH EFFICIENCY 36V 1.5A BUCK LED DRIVER

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 36V. The AL8806 switches at frequencies up to 1MHz. This allows the use of small size external components, hence minimizing the PCB area needed. Max.
