LEDs have practically replaced cold cathode fluorescent lamps (CCFL) in LCD backlight applications used for panels in small devices including smartphones and tablets as well as large appliances and electronics such as TVs, PC monitors, and notebooks. Thanks to their higher luminous efficiency and far smaller form factor, LEDs enable more effective positioning of the light sources behind the panel.

We offer a wide range of DC-DC solutions to efficiently drive LEDs in the widest spectrum of applications and supporting the variety of implementations and topologies found in LED backlights.
