AL8863
60V BUCK LED CONTROLLER WITH FAULT FLAG
Description
The AL8863 is a step-down DC/DC controller designed to drive LEDs with high output current.
The device operates at an input supply
voltage from 4.
5V to 60V.
Series connection of the LEDs provides identical LED currents resulting in uniform brightness and eliminating the need for ballast resistors.
The switching frequency range of AL8863 is from 50kHz to 1MHz.
The wide operating frequency range allows more flexibility on component selection, and also with operating up to 1MHz, it allows the use of smaller size external components, hence minimizing the PCB size and driver board.
The output current of AL8863 is set via an ...
