General Description

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 light output with significantly less input power compared to existing single ended drive schemes.

Key Features
