Controlling multiple LED strings with C2000 MCUs

Page 4
Single and multiple power stage topologies provide an effective approach for efficiently driving multiple LED strings. With its DC/DC LED Lighting Developer’s Kit and Multi-DC/DC Color LED Developer’s Kit, TI offers developers the option of implementing either a single or a multiple power stage topology, while demonstrating various methodologies for LED lighting control. Either approach can be used for most lighting systems, but each has its advantages, depending upon the particular application. Each Piccolo F2802x series microcontroller can control up to eight individual LED strings and, depending upon the power stage design used, drive virtually any number of LEDs per string.

Both kits come with a self-contained GUI-based control application which allows developers to experiment with LED brightness and color control and explore the many versatile capabilities of the Piccolo MCU (see Table 1). Developers can quickly evaluate the different power topologies and control methods, jumpstarting development using the most appropriate method.

TI digital LED controllers provide the highest flexibility and adaptability to changing application requirements. TI also offers an extensive range of analog components backed by years of system-level expertise, comprehensive development tools, and extensive application software to provide developers with a complete LED lighting solution. Using Piccolo MCUs, developers can design systems that balance product price, size, complexity, power efficiency, accuracy, reliability, maintainability, and performance to create the optimal system.
