Output 4W Direct Drive™ CCFL (Cold

Cathode

Module specifically designed for driving

LCD backlight lamps.

driving typical 8.4” to 12.1” panels.

externally programmable over a range of 5

to 6.5mA in 0.5mA steps to allow the

inverter to properly match to a wide array

of LCD panel lamp current specifications.

The modules are include a dimming input

that permits brightness control from either

a DC voltage source, a PWM signal or an

external potentiometer.

LXMG1617 series does not provide wide

range ‘burst’ mode dimming, rather

dimming is provided by amplitude control

of the output current waveform, this limits

the potential dim range to typically less

than 5:1.
