    High-brightness RGB LED popularity for lighting applications is increasing as the cost of these devices becomes more attractive. However, this type of component brings different design complexities when compared to regular LEDs. To efficiently drive high-brightness LEDs, a switched power supply is required and a color mixing algorithm must be implemented. This article describes a simple application in which a digital signal controller (DSC) is used to drive a high-brightness RGB LED for a pixel board, several of which are connected on a network to create an RGB matrix.
