Single Output Inverter. The LXM1612-
lamps.
Technique. Digital Dimming provides
wide-range dimming application.
PWM signal. The resultant 鈥渂urst drive鈥?/div>
that energizes the lamp was designed
specifically to ensure that no premature
lamp degradation occurs.
Input Voltage Range. The modules
convert DC voltage from the system
battery or AC adapter directly to high-
frequency, high-voltage waves required
to ignite and operate CCFL lamps. A 5V
input inverter is also available
(LXM1612-05-xx).
Direct Drive Technology. The module
design is based on a new Direct Drive
topology, which provides a number of
cost and performance advantages.
Additional Features. Other benefits of
this new topology are fixed-frequency
operation and secondary-side strike-
voltage regulation and all LXM1612-12-
xx modules feature both open and
shorted lamp protection.
