NOT RECOMMENDED FOR NEW DESIGN USE AL8860Q OR AL8861Q AL8807BQ AUTOMOTIVE GRADE 30V 1.
3A PWM DIMMABLE BUCK LED DRIVER Description Pin Assignments The AL8807BQ is a step-down DC/DC converter designed to drive LEDs with a constant current.
The device can drive up to 9 LEDs, depending on the forward voltage of the 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 need for ballast resistors.
The AL8807BQ 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...
