电子产品日新月异，不管是硬件工程师还是软件工程师，基本的模电、数电知识也是必备的条件，从二极管到三极管，从单片机到多核MCU，3G网络到5G产品的普及，不管电子产品的集成度怎么高，其产品还是少不了电阻电容电感，每个元器件在电路中必然有其作用，有兴趣了解的网友，下载学习学习吧。

摘要：类似的MAX9704D类音频放大器提供了近90％的效率，但他们需要10V操作。由D类放大器的开关模式升压转换器（MAX1771），它从输入产生12V下降到2V，并提供两个安培的输出电流高达结合，这从一对AA电池可以操作。Maxim>AppNotes>AudioCircuitsKeywords:classDaudioamplifiers,switchmodeboostconverters,AAalkalinecellsAug17,2010APPLICATIONNOTE4526TwoAACellsProduceHugeAudioVolumeAbstract:ClassDaudioamplifiersliketheMAX9704offeralmost90%efficiency,buttheyneed10Vtooperate.Byincorporatingaswitched-modeboostconverter(MAX1771),whichgenerates12Vfrominputsdownto2Vanddeliversoutputcurrentsuptotwoamperes,thisclassDamplifiercanoperatefromapairofAAcells.AsimilarversionofthisarticleappearedintheMarch11,2008issueofElectronicDesignmagazine.ClassDaudioamplifiersfromMaximofferalmost90%efficiency,buttheyneed10Vtooperate,and(forbattery-opera……

摘要：有三种方法来充电锂离子电池开关模式，线性和脉冲。每种方法都有其优点和缺点。广泛的AC适配器电压开关模式充电，最大限度地减少功耗，但消耗更多的电路板空间，并增加了复杂性相比，线性和脉冲充电。线性充电器是小的和伟大的噪声敏感设备，但功耗高。脉冲充电器虽小，效率高，但需要一个电流限制的AC适配器。选择的成本，空间和效率的优先次序为基础的收费方法。Maxim>AppNotes>BATTERYMANAGEMENTKeywords:lithium-ionbattery,Li+,switchmode,switch-modecharging,inearcharging,pulsechargingDec27,2001APPLICATIONNOTE913Switch-Mode,Linear,andPulseChargingTechniquesforLi+BatteryinMobilePhonesandPDAsAbstract:TherearethreemethodstochargingLi+batteries:switch-mode,linearandpulse.Eachmethodhasitsadvantagesanddisadvantages.Switch-modechargingminimizespowerdissipationoverawiderangeofACadaptervoltages,butconsumemoreboardspaceandaddcomplexitycomparedtolinearandpulsecharging.Linearchargersaresmallandgreatfornoisesensitiveequipment,butpowerdissipationishigh.Pulsechargersaresmallandefficient,butrequireacurrent-limitedACadapter.Selectthechargingmethodb……
