Cyntec電原版塊DC/DC電壓(ya)(ya)指整(zheng)流(liu)電壓(ya)(ya)變(bian)換為整(zheng)流(liu)電壓(ya)(ya)的(de)電壓(ya)(ya)，從一(yi)個舉例上看，LDO(低電壓(ya)(ya)差曲線交流(liu)穩壓(ya)(ya)器)處理芯(xin)片(pian)也(ye)想(xiang)必回歸DC/DC電原，但似(si)的(de)只(zhi)將直(zhi)(zhi)流(liu)電壓(ya)(ya)電壓(ya)(ya)切換到直(zhi)(zhi)流(liu)電壓(ya)(ya)電壓(ya)(ya)，且本身(shen)切換手段(duan)步(bu)驟(zou)是(shi)路過(guo)開關按鈕手段(duan)步(bu)驟(zou)搞定的(de)電原分為DC/DC外(wai)接電源。

一個功(gong)率變換(huan)(huan)器，當輸入、負載和控(kong)制均為固定值時(shi)的工作狀態，在(zai)(zai)開(kai)關電(dian)源中，被稱為穩態。穩態下，功(gong)率變換(huan)(huan)器中的電(dian)感滿意電(dian)感電(dian)壓伏秒(miao)(miao)平衡規(gui)律：對于已工作在(zai)(zai)穩態的Cyntec電(dian)源模塊(kuai)DC/DC功(gong)率變換(huan)(huan)器，有源開(kai)關導通(tong)時(shi)加在(zai)(zai)濾波(bo)電(dian)感上的正向伏秒(miao)(miao)必定等于有源開(kai)關截(jie)至時(shi)加在(zai)(zai)該電(dian)感上的反向伏秒(miao)(miao)。

Cyntec電源模塊DC/DC芯片主要是經過反饋電壓與內部基準電壓的(de)的(de)比較，然后調理MOS管(guan)驅動波(bo)形的(de)占空比，來確保輸出電壓的(de)安穩。

由于二極管(guan)導通(tong)(tong)時至少存在(zai)0.3V的壓(ya)降，因此續流二極管(guan)D所耗費的功率將(jiang)會稱(cheng)為(wei)DC/DC電源(yuan)主要(yao)功耗，然(ran)后(hou)嚴重約束(shu)了效率的提高。為(wei)處理該問(wen)題，以導通(tong)(tong)電阻(zu)極小(xiao)的MOS管(guan)替代續流二極管(guan)。然(ran)后(hou)經過控制(zhi)器同時控制(zhi)開關(guan)管(guan)和同步整流管(guan)，要(yao)確保兩(liang)個MOS管(guan)不(bu)能同時導通(tong)(tong)，負責將(jiang)會發生短(duan)路。
