Download the MAX7534 datasheet PDF.
This datasheet also covers the MAX7533 variant, as both devices belong to the same ccfl backlight and lcd contrast controllers family and are provided as variant models within a single manufacturer datasheet.
General Description
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.
Key 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 Shutdown 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. 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 brightness settings are preserved in their respective counters while in shutdown. On power-up, the LCD contr
