碩士 === 國立臺灣大學 === 電子工程學研究所 === 100 === In recent years, portable devices involve several integrated chips with different functionality into the same printed-circuit-board (PCB) for achieving various functions. It needs a highly integrated power management module to reduce the volume and weight in order to keep up with the trend of compact size. Unfortunately, the off-chip inductor and capacitors for the high-efficiency switch-mode DC-DC converters occupy the large PCB area. That results in the extra manufacture cost and the problem for system-on-a-chip (SoC) integration. In other words, a highly integrated power management module is necessary for achieving high performance and small footprint area in today’s power management design.
This paper proposes a ripple based technique hysteresis buck converter, this circuit have better regulation and fast transient response than before. Furthermore, this circuit uses the P compensator to remove the use of the compensation capacitor instead of the conventional PI compensator . However, owing to the change of the compensation method, the load regulation performance should be compensated. Thus, the dynamic dc current scaling is proposed in this paper to enhancement the load regulation performance. In the ch5, the whole measurement results are presented.
