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……

摘要：反激式转换器实现电流限制电源铅酸电池充电。MAX668PPM的控制器限制输出电流，回扫变压器，提供电压的上方和下方的电池电压输入的隔离和灵活性。MAX4375电流检测放大器监视充电电流和使用其内部设计的阈值以下的反激式转换器，可以切换到一个较低的充电电压涓流充电模式比较。Maxim>DesignSupport>AppNotes>BatteryManagement>APP621Keywords:lead-acidbatteries,battery,trickle-charge,boostconverter,flybackconverter,converterAug26,2011APPLICATIONNOTE621SimpleCircuitChargesLead-AcidBatteriesAbstract:Aflybackconverterimplementsacurrent-limitedpowersupplytochargelead-acidbatteries.TheMAX668PPMcontrollerlimitstheoutputcurrent,andtheflybacktransformerprovidesisolationandflexibilityforinputvoltagesbothaboveandbelowthebatteryvoltage.TheMAX4375current-senseamplifiermonitorsthechargingcurrentandusesitsinternalcomparatorthatbelowadesignedthresholdtheflybackconvert……
