The LMX1622
series of Direct Drive CCFL (Cold
Cathode Fluorescent Lamp) Inverter
Modules are specifically designed for
driving two lamp LCD displays. They are
available in two power and input voltage
ranges.

Digital
Technique.
Digital dimming provides
flicker-free brightness control in any wide
range (100:1+) dimming application.
The modules are available with a dim-
ming input that permits brightness control
from either a DC voltage source or
a PWM signal.

The resultant “burst drive” that
energizes
the
lamp
specifically to ensure that no premature
lamp degradation occurs (See the “How
RangeMAX Works” section).
Input Voltage Range.
The modules
convert the DC voltage from a fixed 12V
supply directly to high frequency, high-
voltage waves required to ignite and
operate CCFL lamps. A 5V input inverter
is also available; LXM1612-05 series.
Direct Drive Technology.
The
modules 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, secondary-side strike-voltage
regulation, and both open and shorted
lamp protection. If lamp fails to strike the
inverter will timeout and shutdown.
