RangeMax™ StayLIT™ TM ® LXMG1645-12-5x 12V Quad 5W CCFL Inverter Module P RODUCTION D ATA S HEET DESCRIPTION KEY FEATURES W WW . Microsemi . C OM The LXMG1645-12-51 and LXMG164512-52 are Quad 5W Output CCFL (Cold Cathode Fluorescent Lamp) Inverter Modules specifically designed for driving 15” to 18”quad lamp LCD panels. The inverters include two dimming inputs that provide brightness control, V_BRITE and P_BRITE. A voltage on V_BRITE pin adjusts the lamp current amplitude with 0V providing maximum brightness. The P_BRITE input accepts a low frequency PWM signal which directly controls the lamp drive waveform. This PWM RangeMAX™ Digital Dimming Technique provides flicker-free brightness control over a wide range (typically 50:1+). The maximum output current is externally programmable using the SET1 and SET2 pins on the input connector over a range of 6mA to 7.5mA in 0.5mA steps. This allows the inverter to be properly matched to a wide array of LCD panel lamp current specifications, a function which we call PanelMatch™. In addition the inverter has a dedicated V_STATUS pin that indicates a fault has occurred such as an open or shorted lamp. V_STATUS is an open drain configuration whose output is low during normal operation. When one or more lamps sustain a fault the other lamp(s) will continue to operate and the V_STATUS pin will toggle high. This mode of operation during lamp(s) failure is called StayLIT™ since the panel is able to still remain on although at reduced brightness. Other benefits of this new topology are stable fixed-frequency operation and secondary-side strike-voltage regulation.

This module has been designed to operate over a wide range of input and output conditions. However, best efficiency and performance will be obtained if the module is operated under the condition listed in the ‘R.C.’ column. Min. and Max. columns indicate values beyond which the inverter, although operational, may not function optimally.
