The DIODES™ AL5810 is a constant current Linear LED driver offering an excellent temperature and voltage current stability with output adjustable handling capability. The AL5810 simplifies the design of LED drivers by setting the LED current with an external resistor using standard value resistors.
The AL5810 has an open drain output that can swing from 2.0V up to 60V supply voltage enabling it to drive long LED chains for high-side or low-side LED strings. Its low 0.5V RSET pin is outside of the LED current path and can maintain current accuracy while minimizing the required overheads to regulate the LED current. This reduces its power dissipation when compared to traditional linear LED drivers. It makes it ideal for driving LEDs up to 200mA.
The AL5810 is available in the Wettable Flank W-DFN2020-3 (2mm x 2mm) featuring power dissipation (PD) up to 2W and TO-252 (DPAK) package with PD up to 3.8W.
