DS3984 - 4-Channel Cold-Cathode Fluorescent Lamp Controller

Description

The DS3984 is a 4-channel controller for cold-cathode fluorescent lamps (CCFLs) used to backlight liquid crystal displays (LCDs) in TV and PC monitor applications.

Features

  • High-Density CCFL Controller for LCD TV and PC Monitor Backlights.
  • Can Be Easily Cascaded to Support More Than 4 Lamps.
  • Minimal External Components.
  • Analog Brightness Control.
  • Per-Channel Lamp Control Ensures Equal Brightness Among Lamps and Maximizes Lamp Life.
  • Gate Driver Phasing Minimizes DC Supply Current Surges.
  • Per-Channel Lamp Fault Monitoring for Lamp Open, Lamp Overcurrent, Failure to Strike, and Overvoltage Conditions.
