简化编程脉冲调光错开上的DS3994冷阴极荧光灯(CCFL )控制器

资料介绍
摘要: DS3994是一个4通道冷阴极荧光灯控制器( CCFL )背光液晶显示器,在电视和电脑显示器应用(液晶显示器) 。该设备采用突发调光控制灯的亮度。一个独特的功能允许为每个独立错开的四个通道的突发调光序列的开始。一套四个非易失性寄存器,允许用户编程为每个通道错开。计算器是可以帮助用户确定这些寄存器编程应有的价值。本应用笔记介绍了惊人的突发调光的优势,以及如何访问和使用计算器。

APPLICATION NOTE 3898
Calculator Simplifies Programming the Burst Dimming Stagger on the
DS3994 Cold-Cathode Fluorescent Lamp (CCFL) Controller

Abstract: The DS3994 is a 4-channel controller for cold-cathode fluorescent lamps (CCFL) that backlight liquid crystal
displays (LCDs) in TV and PC monitor applications. The device uses burst dimming to control the brightness of the lamps. A
unique feature allows the start of the burst dimming sequence for each of the four channels to be staggered independently. A
set of four nonvolatile registers allows the user to program the stagger for each channel. A c……
