LXMG1617-12-6x

12V 6W CCFL Programmable Inverter Module

TM

DESCRIPTION

The LXMG1617-12-6x is a Single

Output 6W Direct Drive™ CCFL (Cold

Cathode

Fluorescent

Lamp)

Inverter

Module specifically designed for driving

LCD backlight lamps.

It is ideal for

driving typical 12.1” to 15” TFT panels.

LXMG1617

modules

provide

the

designer with a vastly 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.

RangeMAX™

Digital

Dimming

Technique provides flicker-free brightness

control in any wide range typically (50:1+)

dimming application.

The

resultant

“burst

drive”

that

energizes

the

lamp

was

designed

specifically 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 5V input inverter is also

available (LXMG1617-05-6x).

The modules design is based on

Microsemi’s

new

LX1689

backlight

controller, which provides a number of

cost and performance advantages due to

the controller’s high level of integration.

Other benefits of this new topology

are

stable

fixed-frequency

operation,

secondary-side strike-voltage regulation

and both open/shorted lamp protection

with fault timeout.
