AL5890 Overview
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 es 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.
