Overview
NOT RECOMMENDED FOR NEW DESIGN USE AL8860Q OR AL8861Q AL8807Q HIGH EFFICIENCY LOW 30V 1.
3A AUTOMOTIVE COMPLIANT BUCK LED DRIVER Description Pin Assignments The AL8807Q is a step-down DC/DC converter designed to drive LEDs with a constant current.
Depending on the forward voltage of the LEDs, the device can drive up to nine LEDs in series from a voltage source of 6V to 30V.
Series connection of the LEDs provides identical LED currents resulting in uniform brightness and eliminating the requirement for ballast resistors.
The AL8807Q switches at frequency up to 1MHz with controlled rise and fall times to reduce EMI.
This allows the use of small size external components, hence minimizing the PCB area needed.
Maximum output current of AL8807Q 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.
