Implementing a modular High Brightness RGB LED network

Posted: 07 May 2009 ?? ?Print Version ?Bookmark and Share

Keywords:LED network? power supply switched? controller?

The popularity of using high-power LEDs for lighting applications is increasing constantly, as the cost of these devices becomes more attractive. However, to efficiently drive these LEDs a switched power supply is required.

This application note describes a simple application in which a digital signal controller (DSC) network is used to drive a high-power RGB LED matrix. The MC56F8006 is the Freescale device selected for this application.

The high-speed serial peripheral featured on the DSC ensures fast communication between the network nodes. The color matching control algorithm is managed by the ADC, programmable gain amplifier and PWM modules.
