Key Features

  • make it suitable for use in even the largest LCDs, while its low BOM cost makes it ideal for the entire range of LCD TVs and monitors. The DS3994 can stagger the lamp bursts from each of the four channels. This feature allows scanning backlight schemes for video quality improvement to be implemented using a single CCFL controller IC, making it very simple and inexpensive to provide this enhancement. In addition, staggering the bursts from each channel can be used to minimize current ripple on th.
