Single Output Inverter. The LXM1612-

05-xx series of Direct Drive™ CCFL

(Cold

Inverter

designed for driving LCD backlight

lamps.

Technique.

flicker-free brightness control in any

wide-range dimming application.

dimming input that permits brightness

control from an external potentiometer,

DC voltage source, or PWM signal. The

resultant “burst drive” that energizes the

lamp was designed specifically to ensure

that no premature lamp degradation

occurs.

to ignite and operate CCFL lamps. A

12V input inverter is also available

(LXM1612-12-xx)

design is based on a new Direct Drive

topology, which provides a number of

cost and performance ad-vantages.

this new topology are fixed-frequency

operation and secondary-side strike-

voltage regulation and all LXM1612-05-

xx modules feature both open and

shorted lamp protection.
