LXM1612-12-xx

RangeMAX Wide Range Dimming, Single Output Inverter. The LXM1612-12-xx series of Direct Drive™ CCFL (Cold Cathode Fluorescent Lamp) Inverter Modules are specifically designed for driving LCD backlight lamps.RangeMAX Digital Dimming Technique. Digital Dimming provides flicker-free brightness control in any wide-range dimming application.

The modules LXM1612-12-xx are equipped with a dimming input that permits brightness control from either an external potentiometer, DC voltage source, or PWM signal. The resultant "burst drive" that energizes the lamp was designed specifically to ensure that no premature lamp degradation occurs.

Input Voltage Range. The modules LXM1612-12-xx convert DC voltage from the system battery or AC adapter directly to highfrequency, high-voltage waves required to ignite and operate CCFL lamps. A 5V input inverter is also available (LXM1612-05-xx).

Direct Drive Technology. The module LXM1612-12-xx 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 and secondary-side strikevoltage regulation and all LXM1612-12-xx modules feature both open and shorted lamp protection
