5V 2.2W CCFL Programmable Inverter Module
TM
®
DESCRIPTION
The LXMG1617A-05-2x™ is a Single
Output 2.2W Direct Drive™ CCFL (Cold
Cathode Fluorescent Lamp) Inverter
Module designed for driving LCD
backlight lamps. It is ideal for driving
typical 3.9” to 6.4” TFT panels.
LXMG1617A modules provide the
designer with a superior display brightness
range. This brightness range is achievable
with virtually any LCD display.
The maximum output current is
externally programmable over a range of
3.5 to 5mA in 0.5mA steps (PanelMatch)
to allow the inverter to properly match to a
wide array of LCD panel lamp current
specifications. The modules include a
dimming input that permits brightness
control from a DC voltage source, a PWM
signal or an external potentiometer.
The resultant “burst drive” that
energizes the lamp was designed to ensure
that no premature lamp degradation
occurs, while allowing significant power
savings at lower dim levels.
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 3.3V input inverter is also
available (LXMG1617A-03-2x).
The LXMG1617A modules integrate
the newer highly integrated LX1691B
CCFL backlight controller to provide
wider dimming range (typically 100:1+)
and wider temperature range (-30°C to
80°C) compared to the existing solutions
offered by Microsemi.
Other benefits of the inverter’s
topology include stable fixed-frequency
operation, secondary-side strike voltage
regulation and both open/shorted lamp
protection with fault timeout.
The new LXMG1617A (“A Series”)
modules are designed therefore as a
higher performance near drop-in-
replacement (see BRITE minimum input
voltage level and Burst Frequency) for
those customers and applications
currently using the LXMG1617 inverters.

RECOMMENDED OPERATING CONDITIONS (R.C.)
This module has been designed to operate over a wide range of input and output conditions. However, best efficiency and performance
will be obtained if the module is operated under the condition listed in the ‘R.C.’ column. Min. and Max. columns indicate values beyond
which the inverter, although operational, may not function optimally.
