Overview

AL8862Q AUTOMOTIVE GRADE 55V 1A STEP-DOWN CONVERTER Description The AL8862Q is a step-down DC/DC converter designed to drive LEDs with a constant current.
The AL8862Q operates with an input supply voltage from 5V to 55V and provides an externally adjustable output current 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 frequency up to 1MHz.
This allows the use of smaller size external components, hence minimizing the PCB size.
The AL8862Q integrates the power switch and a high-side output current sensing circuit.
Maximum output current of AL8862Q is set via an exte...
