The AL5890 is a 400V linear constant current LED driver and it provides a cost-effective two pin solution. It has good temperature stability and the current accuracy of ±10% regulated over a wide voltage and temperature range. The AL5890 comes in various 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.
The AL5890 is available in thermally robust PDI123 package.
