Driving High Intensity LED Strings in DC to DC Applications
Abstract Improvements in high brightness LED technology offer enhanced energy efficient lighting solutions in a world where the cost of energy continues to rise along with increased demand. Unlike traditional lighting that has been in existence over the last 50-100 years, LEDs require new driver solutions that address the challenges of providing a constant regulated current to a load that can vary in voltage by +/-30% over process and temperature variation. This paper will focus on driving high brightness LEDs from low voltage DC and AC sources commonly used in lighting applications.
