Single Output Inverter. The LXMG1611

series of Direct Drive™ CCFL (Cold

Modules are specifically designed for

driving LCD backlight lamps.

LXMG1611 excels in applications where

critical parameters include very wide range

dimmability, high efficiency and reliable

fail-safe design in a small form factor.

flicker free brightness control in any wide-

range dimming application. Dimming

ratios greater than 100:1 can be achieved.

Incorporation of a video synchronization

feature allows wide ratio dimming without

the display disturbances and interference

seen with competitive products.
