EDN's Best of Power: LED Drivers

By Staff -- EDN, 5/15/2008

As LEDs increase in brightness and power, they are making their way into applications that no one thought of just a year or two ago. They are now commonplace in lighting areas, rather than just finding use as simple indicators. Designers are turning to high-brightness LEDs for automotive, architectural, signage, and portable lighting. As a result, ICs that take the challenge out of balancing and color-tweaking make life much easier for engineers.
