AL8862
60V 1A STEP-DOWN LED DRIVER
Description
The DIODESTM AL8862 is a step-down DC/DC converter designed to drive LEDs with a constant current.
The AL8862 operates with an input supply
voltage from 5V to 60V and provides an externallyadjustable 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 AL8862 switches at frequencies up to 1MHz.
This allows the use of smaller-sized external components, hence minimizing the PCB size.
The AL8862 integrates the power switch and a high-side output current-sensing circuit.
Maximum output current of the AL8862 is set via an external r...
