一种用于物联网应用的240-nA静态电流、95.8%效率的A2比较器及睡眠时间检测器AOT控制Buck变换器

An ultralow-quiescent current dc-dc buck converter with a single controller is presented to achieve high efficiency over a wide load range for Internet of Things application, which is achieved by utilizing adaptive on-time control topology. An on-demand modulation strategy and sleep-time detector are proposed to attain sub-μA quiescent current consumption under ultralight load condition. The adapt...
