LCD panels have become extremely pervasive, from mobile phones to navigation, portable DVD players, notebooks, monitors, televisions, and even automotive instrument clusters and driver information systems. These panels need a backlighting source, which in the past was CCFL-based but is now dominated by LED light sources.
Allegro offers a variety of LED drivers for backlighting to match varying application requirements for input voltage range, number of LEDs per string, number of strings, and LED current.
These devices are highly integrated, with comprehensive fault protection and excellent performance. As well as devices targeted for consumer applications, AEC-Q100 qualified devices are available with appropriate automotive voltage and temperature ratings.
