Advanced TCA 热插拔控制器监测电源分配

在AdvancedTCA系统中，每个可插拔卡、或前面板被设计带电插入工作的系统中，每个前面板允许高达200W的功率接入，从而最大负载电流可达4A至5A。LTC4261提供了浪涌电流抑制、减少电池供电的危害，最小化电源层的干扰及对供电错误的预测。LTC4261提供了多种功能，同时提供了一个数字接口以便于控制LTC4261的功能。AdvancedTCAHotSwapControllerMonitorsPowerDistributionDesignNote397MitchellLeeIntroductionevenSchottkyrectierspresentaseriousprobleminAdvancedTCAisamodularcomputingarchitecturetermsofbothvoltagedropandpowerdissipation:adevelopedbythePCIIndustrialComputerManufacturersconductingpairdropmorethan1Vanddissipate6W.Groupforuseincentralofcetelecomenvironments.Followingthediodemanufacturer’srecommendations,PICMG3.0denes,amongotherthings,theelectrical8squareinchesofboardareaareneededtosatisfytheandmechanicalattributesofthebackplane,connectorsheatsinkingrequirements.andremovablecardsinthese
