ML4876 Datasheet (Micro Linear) - LCD Backlight Lamp Driver with Contrast

ML4876, LCD Backlight Lamp Driver with Contrast

The ML4876 is an ideal solution for driving small cold cathode fluorescent tubes (CCFL) used in liquid crystal display (LCD) backlight applications.

It provides the dimming ballast control and the contrast control for the LCD display.

By utilizing differential drive the ML4876 can deliver the same l
