碩士 === 雲林科技大學 === 電子與資訊工程研究所 === 98 === In recent years, owing to portable electronic products increase many novel functions. These may not only increase complexity of the circuits but also raise the power consumption. These portable devices have slim, light, and powerful advantages. People always need them to help their life and job comfortable. However, it is an important for energy saving and carbon reduction. How to save more energy and raise the power efficiency for the portable device becomes more and more essential owing to the variety of electronic devices. That is power management control field needs to further discuss to effectively reduce the power consumption. A compact size and high efficient single-inductor multi-output (SIMO) DC-DC converter is proposed. In order to apply to H-bridge multilevel converter circuit of multilevel class-D audio amplifier. Compared to traditional designs, this architecture can be multiple output voltage.
