AL5812EV2: 60V @ 150mA, 3.5 ~ 60 Vin, Linear LED Driver

Summary

The AL5812 is an adjustable Linear LED driver offering excellent temperature stability and output handling capability. The AL5812 simplifies the design of linear and isolated or non-isolated LED drivers by setting the LED current with standard value resistors.

The AL5812 has an open drain output that can swing from 1V up to 60V enabling it drive long LED chains. Its low 0.5V RSET pin is outside of the LED current path and so accuracy is maintained while minimizing the required overhead to regulate the LED current. This reduces its power dissipation when compared to traditional linear LED drivers. This makes it ideal for driving LEDs up to 150mA. Longer LED chains can be driven by tapping VCC from the chain, where the chain voltage may exceed 60V.

The AL5812EV2 evaluation board provides MSOP-8EP package.
