DESCRIPTION
Dual Drive, RangeMAX Wide Range Dimming, Single Output Inverter. The LXM1614 series of Direct Drive™ CCFL (Cold Cathode Fluorescent Lamp) Inverter Modules is specifically designed for driving LCD backlight lamps. Although similar to the RangeMAX LXM1612 wide range dimming inverters, the LXM1614 family offers two separate brightness controls for lamp current amplitude and duty cycle.
