首要的電子設備的核心是半導體芯片。為了前進電路的密度，nxp電源管理芯片的(de)特(te)征尺寸始終朝著減小的(de)趨勢發展，電(dian)(dian)(dian)場強度是(shi)隨(sui)著距離(li)的(de)減小而線(xian)性增加，假設電(dian)(dian)(dian)源(yuan)(yuan)電(dian)(dian)(dian)壓(ya)仍是(shi)原來的(de)5V，產(chan)生的(de)電(dian)(dian)(dian)場強度足以(yi)把芯片(pian)擊(ji)穿。所以(yi)，這樣，電(dian)(dian)(dian)子系統對電(dian)(dian)(dian)源(yuan)(yuan)電(dian)(dian)(dian)壓(ya)的(de)要(yao)求就發生了(le)改變，也便(bian)是(shi)需要(yao)不(bu)同的(de)降(jiang)壓(ya)型電(dian)(dian)(dian)源(yuan)(yuan)。為(wei)了(le)在降(jiang)壓(ya)的(de)同時(shi)堅(jian)持率，一(yi)般會(hui)選用降(jiang)壓(ya)型電(dian)(dian)(dian)源(yuan)(yuan)管理芯片(pian)。

電(dian)(dian)(dian)(dian)源管理(li)芯片(pian)操(cao)控芯片(pian)是在很多范疇有著重要(yao)作(zuo)用的產(chan)品，尤其是在的電(dian)(dian)(dian)(dian)子科技(ji)行(xing)業，電(dian)(dian)(dian)(dian)源管理(li)芯片(pian)操(cao)控芯片(pian)更是扮(ban)演著不可或缺的人物。nxp電(dian)(dian)(dian)(dian)源管理(li)芯片(pian)的腳接一個電(dian)(dian)(dian)(dian)容(rong)(rong)到(dao)地，一個電(dian)(dian)(dian)(dian)阻到(dao)輸入(ru)(ru)電(dian)(dian)(dian)(dian)壓(ya)，上(shang)電(dian)(dian)(dian)(dian)時輸入(ru)(ru)電(dian)(dian)(dian)(dian)壓(ya)經由電(dian)(dian)(dian)(dian)阻給電(dian)(dian)(dian)(dian)容(rong)(rong)充(chong)電(dian)(dian)(dian)(dian)，當(dang)電(dian)(dian)(dian)(dian)容(rong)(rong)上(shang)的電(dian)(dian)(dian)(dian)壓(ya)充(chong)到(dao)芯片(pian)的發起(qi)電(dian)(dian)(dian)(dian)壓(ya)門限值時，芯片(pian)開端(duan)功(gong)課。為了節(jie)能，發起(qi)電(dian)(dian)(dian)(dian)阻都(dou)比(bi)較大，單(dan)靠電(dian)(dian)(dian)(dian)阻電(dian)(dian)(dian)(dian)容(rong)(rong)不能供給堅持芯片(pian)正常功(gong)課所需的電(dian)(dian)(dian)(dian)流，所以要(yao)在高頻變壓(ya)器 上(shang)設一個供電(dian)(dian)(dian)(dian)繞(rao)組給芯片(pian)供電(dian)(dian)(dian)(dian)。
