Full Bridge Resonant CCFL Controller
P RODUCTION D ATA S HEET
DESCRIPTION Microsemi’s LX1696A is a full bridge resonant controller designed specifically for Automotive and high performance display applications. The Direct Drive CCFL (Cold Cathode Fluorescent Lamp) controller is optimized to provide the functions, efficiency, and safety features critical to vehicular applications while providing major advancements in overall component count and costs at the system level. Resonant full bridge topology provides near sinusoidal waveforms over a wide supply voltage range in order to maximize the life of CCFL lamps, control EMI emissions, and maximize efficiency. This new architecture also provides a wide dimming range.
