Manufacturer: Maxim Integrated (now Analog Devices)

Overview: Rev 0; 4/05 .. 8-Channel Cold-Cathode Fluorescent Lamp Controller General.

General Description

The DS3988 is an 8-channel controller for cold-cathode fluorescent lamps (CCFLs) used to backlight liquid crystal displays (LCDs) in TV and PC monitor applications.

The DS3988 supports configurations of 1 to 8 lamps, and multiple DS3988 controllers can be cascaded to support applications requiring more than 8 lamps.

Key Features

  • High-Density CCFL Controller for LCD TV and PC Monitor Backlights.
  • Can Be Easily Cascaded to Support More Than 8 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.
