SLIC的电源设计

系统包括语音服务与数据服务。这种系统使用用户线接口卡（SLIC）功能，以保持与原有设备的兼容性。在这些系统所需要的电压，因国家而异，取决于特定的应用程序。本文讨论了如何在使用MAX668升压控制器等系统所需的各种电压。分裂的反馈意见，以改善交叉调节。还介绍了一个例子是一个孤立的电源。Maxim>AppNotes>AUTOMOTIVEPOWER-SUPPLYCIRCUITSKeywords:SLIC,ringervoltage,on-hook,off-hook,flyback,transformer,boost,snubber,isolatedpower,Jun01,2001customerpremiseequipment,subscriberlineinterface,splitfeedback,flybackpowersupplyAPPLICATIONNOTE904SLICPower-SupplyDesignAbstract:Integratedcommunicationsystemsincorporatevoiceservicewithdataservice.Suchsystemsusesubscriber-lineinterfacecard(SLIC)functionstomaintaincompatibilitywithlegacyequipment.Thevoltagesrequiredinthesesystemsvaryfromcountrytocountryanddependsontheparticularapplication.ThisarticlediscusseshowtoderivevariousvoltagesrequiredinsuchsystemsusingtheMAX668boostcontroller.Splitfeedbacktoimprovecross-regulationispresent
