LXMG1617A-12-6x

12V 6W CCFL Programmable Inverter Module

TM

DESCRIPTION

The LXMG1617A-12-6x is a Single

Output 6W Direct Drive™ CCFL (Cold

Cathode

Fluorescent

Lamp)

Inverter

Module

designed

for

driving

LCD

backlight lamps. It is typically ideal for

driving 12.1” to 15” 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 5

to 8mA in 1mA steps 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 module converts a 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 (LXMG1617A-05-6x).

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) for those customers and

applications

currently

using

the

LXMG1617 inverters.
