500V LINEAR CONSTANT CURRENT LED DRIVER PRODUCT
NEWINFORMATON
ADVANCED Description Pin Assignments
PowerDI123 (Type B) The AL5890 is a 500V linear constant current LED driver and it
provides a cost-effective two pin solution. It has good temperature
stability and the current accuracy of В±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. 1 IN The AL5890 turns on when the voltage between IN and OUT is
greater than 7V. Long LED chain application up to 500V operating
voltage subject to package thermal limitation. 2 В® The AL5890 is available in thermally robust PowerDI 123 (Type B) (Top View) package.
