更高的效率、更紧凑的外形、更低的能耗——这一直是电池供电的电子产品和物联网设备渴望的理想电源产品。

在传统的DC-DC开关稳压器结构中，开关稳压器的每路输出都需要一个独立电感，由于这些电感体积大、成本高，难于减小尺寸。而LDO线性稳压器，外形紧凑、噪声低，但损耗较大。如果选择使用多路低压差稳压器(LDO)和DC-DC转换器，整个系统的又比较复杂，体积也较大……

这时单电感多输出(SIMO)开关稳压器应该是个不错的选择：与传统的DC-DC方案相比，SIMO通过单电感提供多路输出，在节省空间的同时仍然保持高效率，同时低静态特性可有效延长电池寿命。

Maxim In tegrated推出的SIMO开关稳压器就是最具代表性的产品，其将原本需要多个分立元件的功能集成到较小封装，同时具有转换效率高、功耗低的特点，为要求延长电池寿命的小尺寸设备提供了最佳方案。

采用SIMO架构的Maxim Integrated开关稳压器包括一系列产品：

MAX77278：降压-升压稳压器，通过单电感提供3个可独立编程的电源轨，是高集成的电池充电和电源管理解决方案。
MAX77640/MAX77641：集成了三输出降压-升压稳压器、150mA LDO和三通道电流吸收驱动器。
MAX77680/MAX77681：静态电流仅有3μA的三通道降压-升压稳压器，可替代效率低下的LDO。
MAX17270：三输出降压-升压稳压器，效率高达85%。
