The LMX1622 series of Direct Drive CCFL (Cold Cathode Fluorescent Lamp) Inverter Modules are specifically designed for driving two lamp LCD displays. They are available in two power and input voltage ranges. LMX1622 modules provide the designer a vastly superior display bright- ness range. This brightness range is achievable with virtually any LCD display. RangeMAX Digital Dimming Technique. Digital dimming provides flicker-free brightness control in any wide range (100:1+) dimming application. The modules are available with a dim- ming input that permits brightness control from either a DC voltage source or a PWM signal. The resultant “burst drive” that energizes the lamp was designed specifically to ensure that no premature lamp degradation occurs (See the “How RangeMAX Works” section). Input Voltage Range. The modules convert the DC voltage from a fixed 5V supply directly to high-frequency, high- voltage waves required to ignite and operate CCFL lamps. A 12V input inverter is also available; LXM1612-12 series. Direct Drive Technology. The modules design is based on a new Direct Drive topology, which provides a number of cost and performance advantages. Additional Features. Other benefits of this new topology are fixed-frequency operation, secondary-side strike-voltage regulation, and both open and shorted lamp protection. If lamp fails to strike the inverter will timeout and shutdown.
