Product Summary

The LX6523AID-TR is a high performance CCFL controller optimized for small or medium size LCD-TV and other multi-lamp LCD display systems. It enables cost competitive solutions for off-PFC HV-LIPS inverter applications. The controller provides a pair of push-pull PWM drive signals. The output drivers can drive a push-pull, half bridge, or full bridge CCFL inverter configuration with the addition of simple external circuitry. The LX6523AID-TR integrates JIN PureBLACKTM megacontrast digital burst dimming functionality to provide true black mega contrast capabilities for CCFL based displays.

Parametrics

Benefits: (1)Optimal System Cost and Increased Efficiency: Reduced number of power stages increase efficiency at a; (2)reduced overall system BOM easier regulatory agency compliance; (3)Enhanced Image Quality and more Realistic Video: Superior black levels for increased dynamic contrast ratio; Great shadow detail for a more enjoyable viewing experience; (4)Increased Flexibility and Performance: Wide dimming range and multiple architecture support; Ease of implementation; Reduced cost with reduction of external components; (5)Ease of Use and Flexibility: One device supports multiple inverter architectures and applications; Reduces cost by eliminating need for high current external buffer; (6)Reliability, Flexibility, Ease of Use, and Reduced Cost: User configurable, supports multiple panel types and customer need; Enhanced operation at very low duty cycles to avoid false open lamp; (7)protection while detecting true open lamp detection.
