摘要:该电路包括电池充电器(MAX712)处理充电器的电源部分和降压开关稳压器(MAX5089)。通过控制稳压器为电池充电控制器MAX712的行为,生产为7V至16V的输出。从任何能够提供所需的快速充电电流,这种情况必须等于输出电压的总和(二加系列充电电池的数量)乘以1.7V的直流电源。Maxim>AppNotes>BatteryManagementPower-SupplyCircuitsKeywords:switchmodebatterychargers,NiMH/NiCdbatterychargers,stepdownregulators,constant-currentsupplies,dV/dtterminationAug09,2010APPLICATIONNOTE4496NiMH/NiCdSwitchmodeBatteryChargerHasdV/dtChargeTerminationAbstract:Thiscircuitincludesabatterycharger(MAX712)andstep-downswitchingregulator(MAX5089)forhandlingthepowerportionofthecharger.BycontrollingtheregulatortheMAX712actsasabattery-chargecontroller,producingoutputsof7Vto16V.ItoperatesfromanyDCsourcecapableofdeliveringthedesiredfast-chargecurrent,withthiscondition:theoutputvoltagemustequal1.7Vmultipliedbythesumof(twoplusthenumberofbatteriestobechargedinseries).Asimilarv……
