摘要：新一代IC与被动元件的改进，使电荷泵电压转换最惠国待遇的做法在许多应用中的结合。在许多情况下，早期的电荷泵被认为是不适宜的或只接受与妥协。例如，一个应用程序，轻松的精确度，低负载电流，高噪声容限，最小的效率需要可以受益于一个电荷泵的成本更低，尺寸更小，电路简单，和当然电感自由运作。Maxim>Designsupport>Appnotes>BatteryManagement>APP669Maxim>Designsupport>Appnotes>Power-SupplyCircuits>APP669Keywords:chargepump,inductorless,powersupply,dcdc,dc-dc,DC-DCSep06,2001APPLICATIONNOTE669ChargePumpsShineinPortableDesignsAbstract:New-generationICshavecombinedwithpassive-componentimprovementstomakecharge-pumpvoltageconversionafavoredapproachinmanyapplications.Inmanycases,theearlierchargepumpswereconsideredeitherunsuitableoracceptableonlywithcompromise.Forexample,anapplicationthathadrelaxedaccuracy,lowloadcurrent,highnoisetolerance,andminimalneedforefficiencycould……
