AL8808 - Diodes

AL8808 COST EFFECTIVE LOW EMI 30V 1A BUCK LED DRIVER

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. T.
