Output Direct Drive™ CCFL (Cold

Cathode

Module specifically designed for driving

LCD backlight lamps.

driving typical 6.4” to 10.4” TFT panels.

dimming input that permits brightness

control from either a DC voltage source or

a PWM signal or external Potentiometer.

The maximum output current is 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.

LXM1623 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.
