Outline of Final Research Achievements

In recent years, a power supply on chip (SoC) has been attracted attentions of many researchers because itrealize ultimate miniaturization of a power supply. However it can handle small capacity per POL and is necessary to connect parallel at heavy loading conditions. In addition, high-frequency switching of more than 10MHz is required for shrinking the volume of the POL. In this study, we propose the novel concept of digitally controlled POLs suitable for power SoC. We also report the simulation and experimental results of the proposed concept. The results show that the proposed concepts enables to regulate output voltage and improves the efficiency over the wide range.
