Output 6W Direct Drive™ CCFL (Cold

Module specifically designed for driving

LCD backlight lamps.

driving typical 12.1” to 15” panels.

externally programmable over a range of 5

to 8A in 1mA 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.

LXM1617 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.
