The LXM1610 series of Direct DriveTM CCFL (Cold Cathode Fluorescent Lamp) Inverter Modules are specifically designed for driving LCD backlight lamps. They excel in applications where critical parameters include dimmability, high efficiency and reliable fail-safe design in a small form factor. These inverters are recommended for use in panels with low-voltage insulation on the lamp return wire. Wide Input Voltage Range. The modules convert unregulated DC voltage from the system battery or AC adapter directly to high-frequency, high-voltage waves required to ignite and operate CCFL lamps. Input voltage can range from 8 to 18 volts. Direct Drive Technology. The module design is based on a new Direct Drive topology, which provides a number of cost and performance advantages. The LXM1610-01 series Direct Drive inverters eliminate the classic resonant inductor and capacitors, thus reducing cost and allowing a 30% reduction in module size. Fixed-Frequency Operation. Other benefits of this new topology are fixedfrequency operation and secondary-side strike-voltage regulation. Strike-voltage regulation minimizes corona discharge in the output transformer and related circuitry, providing longer life and higher reliabi...
