本文提出了一种面向一次性物联网（IoT）设备的高效升降压DC-DC转换器，实现了96.8%的峰值效率。该转换器支持连续输入/输出电流，并通过可重构拓扑结构优化了不同电池电压下的性能，解决了标准碱性电池供电下长寿命与低成本的需求。
Taehwang Kong2, Sang-Ho Kim2, Sungyong Lee2, Michael Choi2, Jongshin Shin2, Gyu-Hyeong Cho1, Hyun-Sik Kim1 KAIST, Daejeon, Korea Samsung Electronics, Hwaseong, Korea 1 2 As internet-of-things (IoT) devices continue to be installed everywhere, the concept of disposable IoT is emerging owing to better cost-efficiency and ease of maintenance without battery recharging. Lasting several years, IoTs powered with standard alkaline batteries can be a promising solution due to the long shelf life, low cost, and high reliability of these batteries as compared to the Li-ion type. As shown in the top portion of Fig. 11.8.1, a single alkaline cell has a maximum voltage of 1.5V, but it can decay down to 0.9V [1]. To power an IoT device operating with VDD=2V, a variety of design options can be considered, such as the battery configuration and the power conversion topology, as shown in Fig. 11.8.1 (bottom). The first approach is step-down conversion [2, 3] from multi-cell
