AL5890

400V Constant Current LED Driver

Description

Pin Assignments (Top View)

The AL5890 is a 400V constant current LED driver and it provides a

cost-effective two pin solution. It has good temperature stability and

the current accuracy of < 2.0mA (typ.) regulated over a wide voltage

and temperature range. The AL5890 comes in various or pre-fixed

output current options removing the need for external current setting

resistors and creating a simple driver solution for the series of LEDs.

The AL5890 supports both the high-side and low-side driving of LED

chains.

The AL5890 turns on when the voltage between IN and OUT is

greater than 7V. Long LED chain application up to 400V operating

voltage subject to package thermal limitation.
