AUTOMOTIVE GRADE BUCK LED DRIVER
Description
Pin Assignments
The AL8806Q 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 AL8806Q 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 AL8806Q is set via an external resistor
connected between the VIN 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.
The AL8806Q has been qualified to AEC-Q100 Grade 1 and is
Automotive Grade supporting PPAPs
