The modules convert the DC voltage from the system battery or AC adapter directly to the high frequency, highvoltage waves required to ignite and operate CCFL lamps. A 5V input wide dimming inverter is also available (LXMG1627-05-6x), as well as a 4W version (LXMG1628-12-4x) for driving smaller lower power/voltage panels. The inverter's design is based on Microsemi's newer 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 and short protection with fault timeout.
