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。Maxim>AppNotes>DISPLAYDRIVERSPOWER-SUPPLYCIRCUITSKeywords:DS3994,CCFL,burstdimming,calculator,cold-cathodefluorescentlamp,LCDSep11,2006APPLICATIONNOTE3898CalculatorSimplifiesProgrammingtheBurstDimmingStaggerontheDS3994Cold-CathodeFluorescentLamp(CCFL)ControllerAbstract:TheDS3994isa4-channelcontrollerforcold-cathodefluorescentlamps(CCFL)thatbacklightliquidcrystaldisplays(LCDs)inTVandPCmonitorapplications.Thedeviceusesburstdimmingtocontrolthebrightnessofthelamps.Auniquefeatureallowsthestartoftheburstdimmingsequenceforeachofthefourchannelstobestaggeredindependently.Asetoffournonvolatileregistersallowstheusertoprogramthestaggerforeachchannel.Ac……
