    多输出转换开关降压电路和两个积极的线性稳压器组成。虽然该集成电路的基本应用电路提供了一个低成本的多输出电源,需要目前有限的线性稳压器输出(开关降压已是当前有限)的设计,需要咨询本应用笔记。如果短裤线性稳压器的输出,或失误可能会导致功耗的外部旁路元件将超过预期,应采用限流。与折返电流限制电路,就可以了进一步的保护。本应用笔记详细的设计和实施当前限制MAX1864积极的线性稳压器的。Maxim>AppNotes>AUTOMOTIVEKeywords:Currentlimit,foldback,foldback,linearregulator,lead-acidbatteryNov16,2005APPLICATIONNOTE3654CurrentLimitingfortheMAX1864AuxiliaryRegulatorAbstract:TheMAX1864isalow-cost,multiple-outputconverterconsistingofaswitchingbuckcircuitandtwopositivelinearregulators.Althoughthisintegratedcircuit'sbasicapplicationcircuitoffersalowcostmultipleoutputsupply,designsthatrequirecurrentlimitedlinearregulatoroutputs(theswitchingbuckisalreadycurrentlimited)needtoconsultthisapplicationnote.Ifshortsareexpectedatthelinearregulatoroutputs,orwheremishapscancausethepowerdissipationoftheexternalpasselementtobeexceeded,currentlimitingshouldbeemployed……
