Output Direct Drive™ CCFL (Cold

Cathode

Module specifically designed for driving

LCD backlight lamps.

driving typical 10.4” to 15” 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 8mA in

1mA 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.
