LTC3526是一款高集成度的升压DC/DC转换器，mm×2mm封装使其就在于电池供电应用中。低启动电压和工作电压延长了单电池应用的工作时间。当采用新电池时，其电压可能超过VOUT值，则LTC3526甚至会实现降压式工作，在高效、轻负载和低噪声工作时，LTC3526提供了突发模式或固定频率工作模式。TinySynchronousStep-UpConverterStartsUpat700mVDesignNote428DaveSalernoIntroductionatypicalstartupvoltageofjust700mV,withoperationAlkalinebatteriesareconvenientbecausethey’reeasytodownto400mVoncestarted.DespitetheLTC3526L’sndandrelativelyinexpensive,makingthemthepowertinysolutionsize,itincludesmanyadvancedfeatures,sourceofchoiceforportableinstrumentsanddevicesincludingoutputdisconnect,shortcircuitprotection,lowusedforoutdoorrecreation.Theirlongshelflifealsonoisexedfrequencyoperation,internalcompensation,makesthemanexcellentchoiceforemergencyequipm……
