Description

The LX1995 Evaluation Board (EB) is available from Microsemi for evaluating the performance of the LX1995
LED driver integrated circuit. (See picture 1) The EB contains a small amount of support circuitry that enhances
performance in different dimming configurations. (See schematic 1.) In a typical application, some of this circuitry
would be eliminated.
