A matter of light, Part 1---The ABC's of LEDs
Here's the basics on LED parameters and what you need to know about their drivers.

A matter of light, Part 2--- Buck whenever possible
Here's why a constant-current buck converter should be the first preference when it comes to switch-mode LED drivers.

A matter of light, Part 3---When to boost and buck-boost
In this third installment, we investigate larger LED displays and the applications space for other converter topologies.

A matter of light: Part 4 - PWM dimming
Digital dimming with a buck regulator provides the best LED driving topology.


DESIGNING WITH LEDS From Embedded.com
LEDs shine as replacement for lightbulb
Researchers create a better white light-emitting diode (LED) by embedding yellow, green and red luminescent nanoparticles into a fluorescent blue polymer matrix and pump the hybrid organic/inorganic material with a near ultra-violet LED.

Integrated drivers prove their worth in demanding auto high-brightness LED apps
Engineers serving the automotive sector need to be fully aware of what driving options are most suitable if the benefits of high-brightness LEDs are to be fully realized.
