RangeMAX Wide Range Dimming, Single Output Inverter. 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.LXM1611-01 are equipped with a dimming input that permits brightness control from an external potentiometer or DC voltage source. The resultant "burst drive" that energizes the lamp was designed specifically to ensure that no premature lamp degradation occurs. (See"How RangeMAX Works" Section)
Wide Input Voltage Range. The modules LXM1611-01 convert unregulated DC voltage from the system battery or AC adapter directly to highfrequency, high-voltage waves required to ignite and operate CCFL lamps.
Direct Drive Technology. The module design is based on a new Direct Drive topology, which provides a number of cost and performance advantages. The LXM1611-01 series Direct Drive inverters eliminate the classic resonant inductor and capacitors, thus reducing cost and allowing a 30% reduction in module size.Additional Features. Other benefits of this new topology are fixed-frequency 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 reliability. All LXM1611 modules feature both open and shorted lamp protection.
The LXM1611 is fully customizable (electronically and mechanically) to specific customer requirements.
