♦ Drives Backplane and Backlight

♦ 4V to 30V Battery Voltage Range

♦ Low 500µA Supply Current

The MAX753/MAX754 drive cold-cathode fluorescent

lamps (CCFLs) and provide the LCD backplane bias

(contrast) power for color or monochrome LCD panels.

These ICs are designed specifically for backlit note-

book-computer applications.

♦ Digital or Potentiometer Control of CCFL

Brightness and LCD Bias Voltage

Both the backplane bias and the CCFL supply can be

shut down independently. When both sections are shut

down, supply current drops to 25µA. The LCD contrast

and CCFL brightness can be adjusted by clocking sep-

arate digital inputs or using external potentiometers.

LCD contrast and backlight brightness settings are pre-

served in their respective counters while in shutdown.

On p owe r-up , the LCD c ontra s t c ounte r a nd CCFL

brightness counter are set to one-half scale.

♦ Negative LCD Contrast (MAX753)

♦ Positive LCD Contrast (MAX754)

♦ Independent Shutdown of Backlight and

Backplane Sections

♦ 25µA Shutdown Supply Current

The ICs are powered from a regulated 5V supply. The

magnetics are connected directly to the battery, for

maximum power efficiency.

______________Ord e rin g In fo rm a t io n

The CCFL driver uses a Royer-type resonant architec-

ture. It can provide from 100mW to 6W of power to one

or two tubes. The MAX753 provides a negative LCD

bias voltage; the MAX754 provides a positive LCD bias

voltage.
