描述 Description

The LXMG1813-12-6xS is a Single Output 6W CCFL (Cold Cathode Fluorescent Lamp) Inverter Module designed for the driving LCD backlight lamps for panels in the range of 3.9” to 15”. Utilizing the full-bridge drive topology capabilities of the Microsemi’s highly integrated LX1697 CCFL backlight controller the inverter allows a wider input voltage range (9V to 16.8V) and wider lamp output voltage range 390V to 790V compared to Microsemi’s existing Direct Drive™ inverter solutions. Also this ‘S’ version includes an additional input connector which links the inverter to a light sensor board (the LXMG1800_LS). So connected, the inverter is capable of automatically adjusting (VEasyLIT™) the brightness of the LCD display to ambient lighting conditions. Automatic brightness control can extend the life of the display and save power (particularly important for battery powered products). For applications needing full manual control of lamp brightness (dimming) we recommend the LXMG1813-12-6x (non-S), which does not offer the light sensor input. The maximum output current of the inverter is externally programmable over a range of 4mA to 7mA in 1mA steps to allow the inverter to properly match (PanelMatch™) to a wide array of LCD panel lamp current specifications. For lower input voltage requirements the LXMG1811-05-6x or -6xS will work from a 5V input supply. Other benefits of the inverter’s topology include stable fixed-frequency operation, secondary-side strike voltage regulation and both open/shorted lamp protection with fault timeout.  ROHS
