Features
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, 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
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.
