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……
