MAX7534 - CCFL Backlight and LCD Contrast Controllers

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.

19-0197; Rev 1; 1/95 CCFL Backlight and LCD Contrast Controllers _______________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. 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 contrast counter and CCFL brightness counter are set to one-half scale.
