APPLICATION NOTE 4048
Use a DS3882 CCFL Controller to Drive a Two-Lamp Common-
Return Configuration

Abstract: This application note describes a backlight LCD application in which two adjacent CCFL lamps share a
common, low-voltage side lamp connection. This design is found in automotive, industrial, and avionic
applications. The article describes how a DS3882 CCFL controller can be used to drive the two CCFL lamps that
share a common return.


Introduction

The DS3882 is a two-channel controller for cold-cathode fluorescent lamps (CCFL) that backlight liquid crystal
displays (LCD) in automotive, industrial, and avionic application……
