AL8807
HIGH EFFICIENCY LOW 36V 1A BUCK LED DRIVER
Description
The AL8807 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 36V. Series connection of the LEDs provides
identical LED currents resulting in uniform brightness and eliminating
the need for ballast resistors. The AL8807 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 AL8807 is set via an external resistor
connected between the V IN 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.
