隨著在系統單晶片(System on Chip, SOC)在手持裝置以及面板的發展下,更小的面積或是更小的電壓、電流漣波以及能夠輸出多組電壓的轉換器需求,本論文提出利用三階層單電感雙輸出的方式以改善此應用場合,主要特色為三階層降壓型轉換器能夠將電流漣波變小,在需要相同大小的漣波下,能夠將電感的大小縮小,達到節省面積的功能,並且使用電壓模式控制加上將電容電壓回授的方式。同時利用單電感雙輸出的方式能夠達到只使用一組降壓型轉換器達到多輸出的方式,取代先前需要做多組轉換器以達到相同效果。
本論文採用TSMC 0.18 μm 1P6M CMOS製程實現,晶片的面積包含內部PADs為2.23×2.2 mm2 。本文輸入電壓為3.3 V,供應電壓為3.3 V以及1.8 V、輸出電壓分別為1.8 V以及1.2 V,切換頻率為2~4MHz,PCB上面外掛電感以及輸出電容分別為1μH與10 μF,輸出負載範圍為200 mA至800 mA。
Development of system-on-chip (SoC, system-on-chip) handheld devices and panel device, converter will want to achieve more smaller area and the ripple of the voltage and current, and need more output voltage to drive the after-stage circuit. This thesis show the method of three-level single inductor dual output, the characteristic of three-level converter is can reduce the ripple of current, when we need the same ripple, it can reduce the area of the inductor, and use flying capacitor feedback voltage mode to control it. Simultaneously, use single inductor dual output method can use one buck converter to reach multiple output.
