The LXM1611 series of Direct DriveTM CCFL (Cold Cathode Fluorescent Lamp) Inverter Modules are specifically designed for driving LCD backlight lamps. Similar to the LXM1610, the LXM1611 excels in applications where critical parameters include very wide range dimmability, high efficiency and reliable fail-safe design in a small form factor. Unlike the LXM1610 or any traditional dimming CCFL inverters, the LXM1611 provides the designer a vastly superior display brightness range. 100:1+ brightness range is achievable with virtually any LCD display. Our wide range dimming provides exceptional display readability at less than 1% of full brightness, allowing both power savings and low ambient light operating capability (i.e. "night readable"). The LXM1611 is recommended for use in panels with low-voltage insulation on the lamp return wire. RangeMAX Digital Dimming Technique. Digital dimming provides flickerfree brightness control in any wide-range dimming application. Dimming ratios greater than 100:1 can be achieved. Incorporation of a video synchronization feature allows wide ratio dimming without the display disturbances and interference seen with competitive products. The mod...
