Overview
The LXMG1627-05-44 is a Dual 4W Output Direct Drive™ CCFL (Cold Cathode Fluorescent Lamp) Inverter Module specifically designed to be compatible with the Sharp LQ104S1DG51 /61 10.4”, LQ121S1DG41/61 12.1” as well as the 10.4” Toshiba Matsushita LTA104D182F/183F and the Samsung LTM121SI-T01 12.1” or similar dual lamp displays that have individual lamp output connectors on one side of the panel. LXMG1627 modules provide the designer with a vastly superior display brightness range. The RangeMAX™ Digital Dimming Technique supplies flicker-free brightness control for any wide range (typically 50:1+) dimming application. The included dimming input permits brightness control from either, a DC voltage source, a PWM signal or an external potentiometer. The maximum output current is externally programmable (through the input connector) over a range of 5mA to 6.5mA in 0.5mA steps. This allows the inverter to match the panel’s lamp current specifications. The modules convert a DC voltage from the system battery or AC adapter directly to high frequency, high-voltage waves required to ignite and operate CCFL lamps. A 12V input inverter version is also available: LXMG1627-12-44. The module’s design utilizes Microsemi’s LX6512 backlight controller, which provides a number of cost and performance advantages due to the controller’s high level of integration. Other benefits of this new topology are stable fixed-frequency operation, secondary-side strike-voltage regulation and both open/shorted lamp protection with fault timeout for open lamp condition. The new LXMG1627-xx-44 modules are designed therefore as a wider temperature range near drop-in-replacement for the LXMG1623-xx-44 inverters, the major difference being the input voltage adjustment range of the BRITE (dimming) pin. |
