DIODES™ AL5810 Linear LED Driver

Featuring excellent temperature and voltage current stability

The DIODES™ AL5810 Linear LED Driver is a constant current device that brings superior temperature and voltage current stability while offering output adjustable handling capabilities. It is highlighted for its simplified design, as it sets the LED current through an external resistor using standard value resistors.

The AL5810 offers a great range of open drain output, swinging from 2.0V up to 60V supply voltage, resulting in long LED chain driving capabilities for high or low side LED strings. With a low 0.5V RSET pin outside the LED current path, the AL5810 maintains a superior accuracy as it minimizes overheads needed to regulate current. In addition, this powerful solution reduces power dissipation compared to traditional linear LED drivers, making it ideal for driving LEDs up to 200mA.
