MAX7533 CCFL Backlight and LCD Contrast Controllers

MAX7533 Description

19-0197; Rev 1; 1/95 CCFL Backlight and LCD Contrast Controllers _______________General .
The MAX753/MAX754 drive cold-cathode fluorescent lamps (CCFLs) and provide the LCD backplane bias (contrast) power for color or monochrome LCD panels.

MAX7533 Features

* o Drives Backplane and Backlight o 4V to 30V Battery Voltage Range o Low 500µA Supply Current o Digital or Potentiometer Control of CCFL Brightness and LCD Bias Voltage o Negative LCD Contrast (MAX753) o Positive LCD Contrast (MAX754) o Independent Shutdown of Backlight and Backplane Sections o 25µA

MAX7533 Applications

* 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 separate digital inputs or using external potentiometers. LCD contrast and backlight brightnes
