In 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 In 1 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 2 voltage subject to package thermal limitation. Out The AL5890 is available in thermally robust PowerDI 123 (Type B), PowerDI123 (Type B) SOT89 and TO252 (Standard) packages. 1 Features DC up to 400V Operating Voltage With Long LED Chains Out 2 Subject to Package Thermal Constraint LED Current Tolerance Over Wide Temperature Range < 2.0mA (typ.)

Stresses greater than the Absolute Maximum Ratings specified above may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions exceeding those indicated in this specification is not implied. Device reliability may be affected by exposure to absolute maximum rating conditions for extended periods of time. Semiconductor devices are ESD sensitive and may be damaged by exposure to ESD events. Suitable ESD precautions should be taken when handling and transporting these devices. 2 of 17 AL5890 May 2018 Diodes Incorporated www.diodes.com Document number: DS40280 Rev. 2 - 2 ADVANCNEEDW I NPRFOORDMUCATT ON
