本論文提出以漣波控制模式為基礎之單電感四輸出降壓型轉換器，並使用循序功率分配法將電感能量有效分配至各負載端。此降壓型轉換器加入一獨特之類比架構，實現單電感多輸出的效果。此外，本研究加入了自適應截止時間控制電路來降低因非理想效應引起的切換頻率變動的影響。本電路的實現為功率級輸入電壓3.8V，輸出電壓分別為0.9V/1.2V/1.5V/1.8V，負載變動範圍50-200mA。實測所得之切換頻率將在13-20kHz進行變動，且暫態時間上升與下降將在3到4個週期內完成，交互穩壓率為1.3 mV/mA。

This thesis introduces a single-inductor Quad-output buck converter employing ripple-based control and an order-power distribution method to efficiently distribute energy to each load. The buck converter employs a distinctive analog architecture to achieve a single inductor multiple outputs mechanism. Furthermore, this study presents an adaptive off-time control circuit to mitigate the effects of switching frequency variations caused by non-ideal effects. The proposed control was implemented on a power stage with an input voltage of 4.2V and output voltages of 0.9V, 1.2V, 1.5V, and 1.8V, accommodating load variations ranging from 50mA to 200mA. Test results reveal that the switching frequency ranges from 13kHz to 20kHz under light to heavy loads, respectively. Additionally, the rising and falling recovery times are consistently kept within 3 to 4 cycles, and the cross-regulation is measured at 1.3mV/mA.
