NEW PRODUCT AL8808 COST EFFECTIVE LOW EMI 30V 1A BUCK LED DRIVER Description The AL8808 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. Series connection of the LEDs provides identical LED currents resulting in uniform brightness and eliminating the need for ballast resistors. The AL8808 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 AL8808 is set via an external resistor connected between the VIN and SET input pins.
