| .COM RangeMAX LXM1614E-14-11 DUAL DIMMING, EXTENDED TEMPERATURE CCFL INVERTER MODULE PRELIMINARY DATASHEET Dual Drive, RangeMAX Wide Range Dimming, Single Output Inverter. The LXM1614E series of Direct Drive CCFL Cold Cathode Fluorescent Lamp Inverter Modules is specifically designed for driving LCD backlight lamps. Although similar to the RangeMAX LXM1612 wide range dimming inverters, the LXM1614E family offers two separate brightness controls for lamp current amplitude and duty cycle. This innovation of dual brightness control with extended dimming, combined with Microsemi’s high efficiency Direct Drive topology, provides the industry’s most feature rich, small form factor inverter available. The wide range dimming provides exceptional display readability at less than 1% of full brightness, allowing both power savings and low ambient light operating capability. Dual Drive Dimming Control. The inverters provide brightness adjustments utilizing standard lamp current amplitude control as well as supporting Microsemi’s RangeMAX wide range dimming technique. Combining both brightness controls into a single inverter supports the “self heating” lamp technology by using a “boost” current feature and still offers duty cycle control for low brightness operation. This controlled overdrive capability eliminates the need for traditional resistive heater wire methods to ensure light output at extremely low temperatures. The LXM1614E brightness controls support temperature monitoring with look-up table applications by accepting either a PWM input or DC voltage. Large panel lamps with greater thermal inertia can also utilize this “instant-bright” feature and minimize warm up time. continued next page IMPORTANT For the most current data, consult MICROSEMI’s website Protected by U.S. Patents 5,923,129 5,930,121 Patents Pending PRODUCT HIGHLIGHT KEY FEATURES Independent Brightness Controls For Lamp Current Amplitude and Duty Cycle RangeMAX 1-100% Wide Range Dimming with Controlled Overdrive Boost On-Board Thermister automatically limits maximum lamp current Supports Wide Input Voltage Range 9-16V High Efficiency, Single Stage Direct Drive Topology -40°C to +85°C Ambient Temperature Operation Output Open/Short Circuit Protection Up to 2000V Output Voltage Capability Single side PCB Component Layout Self Heating And High Pressure Lamp Technology Automotive Navigation, GPS Systems, Auto PC Extended Cold Temperature Operation Aircraft Cabin Displays Low Ambient Light Conditions Requiring Wide Range Dimming “Instant On” To Full Brightness For Large LCD Backlight Panels Industrial Notebook And Workstations Controlled overdrive mode of LXM1614E Inverter accelerates lamp warm-up time to provide maximum light output even in extreme temperature environments LXM1614E-14-11 LXM1614E-14-11 MODULE ORDER INFO OUTPUT CONNECTOR JST SM02 8.0 B-BHS-1-TB INVERTER MATES DIRECTLY TO PANEL CONNECTORS BHR-03VS-1 Microsemi Microsemi Integrated Products 11861 Western Avenue, Garden Grove, CA. 92841, 714-898-8121, Fax 714-893-2570 .COM RangeMAX LXM1614E-14-11 DUAL DIMMING, EXTENDED TEMPERATURE CCFL INVERTER MODULE |
