Intelligent LED lighting control with the ultra-low-power MSP430F51x2 microcontrollers

Lighting accounts for about 2,200 terawatt hours (TWh) per year—almost one-fifth of total worldwide energy consumption. This number will grow by 80% unless the world adopts more energy efficient technologies and policies. This paper illustrates an example of an efficient digital power stage topology design for portable applications requiring multiple LED strings (white or RGB) while utilizing capacitive touch for dimming with TI's ultra-low-power microcontrollers.
