Diodes Incorporated AL8862Q Buck LED Driver is a step-down DC-DC converter that drives LEDs with a constant current. The AL8862Q operates with an input supply voltage from 5V to 55V, providing an externally adjustable output current of up to 1A. Series connection of the LEDs provides identical LED currents, resulting in uniform brightness and eliminating the need for ballast resistors. The AL8862Q switches at frequencies up to 1MHz. This feature allows smaller external components to minimize the PCB size.
