DS3882控制器冷阴极荧光灯（CCFL）是背光的液晶显示器在汽车，工业和航空电子应用（液晶显示器）。在这些应用中，CCFL灯管可以要求高罢工电压。虽然一些系统的设计标准影响罢工电压的，一个标准很容易被修改，增加灯泡罢工电压：灯泡罢工过程中提高工作频率。Maxim>AppNotes>AUTOMOTIVEKeywords:CCFL,cold-cathodefluorescentlamps,LCD,liquidcrystaldisplays,automotiveNov02,2006APPLICATIONNOTE3941WhyandHowtoImplementaFrequencyBoostDuringaCCFLLampStrikeontheDS3881/DS3882Abstract:TheDS3881andDS3882arecontrollersforcold-cathodefluorescentlamps(CCFLs)thatbacklightliquidcrystaldisplays(LCDs)inautomotive,industrial,andavionicapplications.IntheseapplicationstheCCFLlampscanrequireahighstrikevoltage.Whileseveralsystemdesigncriteriaaffectthestrikevoltage,onecriterioniseasilymodifiedtoincreasethelampstrikevoltage:boostingtheoperatingfrequencyduringthelampstrikeprocess.ThisapplicationnotedescribestheneedforincreasingtheCCFLcontrolle……

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……
