Backlighting BLU

Fairchild's backlighting ICs are used for all television and monitor applications, including PDP TVs, LCD TVs & Monitors, and LED TV & Monitors. Our solutions help you to achieve slim and sleek form factors. These controllers deliver higher power density, while maintaining high reliability. 

These backlighting inverter drive ICs use a proprietary phase-shift method that controls boost, push-pull topology or full-bridge topologies. These drive ICs provides a low-cost solution and reduce external components by integrating full-wave rectifiers for open-lamp protection and regulation.
