Output Direct Drive™ CCFL (Cold

Cathode

Module specifically designed for driving

LCD backlight lamps.

driving typical 10.4” to 15” TFT panels.

designer with a vastly superior display

brightness range. This brightness range is

achievable with virtually any LCD display.

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.

Technique provides flicker-free brightness

control in any wide range typically (50:1+)

dimming application.
