This is the first part of Fairchild Semiconductor's five part blog series that will examine LED lighting trends and Fairchild solutions. LED lighting applications fall into three basic input power levels: low-power is less than or up to 20 Watts; mid-power is between 20 Watts and 50 Watts; and high-power is above 50 watts. In the real-world, applications do not always fit nicely in these three buckets, but these power levels align when considering LED driver solutions.
