AL5810
ADJUSTABLE 60V LINEAR LED DRIVER
Description
Pin Assignments
The DIODESTM 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.
W-DFN2020-3/SWP (Type A)
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.
