孤立的SLIC电源

摘要：本应用笔记显示了电源产生三个隔离电压SLIC组件。隔离电源使用-24V类型学在反激式变压器，升压控制器MAX668，-72V输出，光耦隔离反馈信号。线性稳压器MAX8867，提供3.3V输出。Maxim>AppNotes>AutomotivePower-supplycircuitsKeywords:subscriberlineinterfacecard,SLIC,boostcontroller,transformerflybacktypology,optocoupler,shuntvoltageregulator,linearJun14,2002voltageregulatorAPPLICATIONNOTE1115IsolatedSLICsupplyAbstract:ThisapplicationnoteshowsapowersupplythatgeneratesthreeisolatedvoltagesforSLICs.Theisolatedpowersupplyusesaboostcontroller,theMAX668,withatransformerinflybacktypologyfor-24V,and-72Voutputs,andisolatesthefeedbacksignalwithanoptocoupler.Alinearvoltageregulator,theMAX8867,providesthe3.3Voutput.AsimilarversionofthisarticleappearedintheSeptember24,2001issueofEETimesmagazine.Somesubscriberlineinterfacecards(SLICs)requirepower-supplyvoltag
