電源管理芯片是在電子設備體系中承擔電源轉化、分配、檢測等電源管理職責的芯片。電源管理集成電路IC是電子設備體系中擔任電能轉化、分配、檢測等電源管理的芯片。它首要擔任將電源電壓和電流轉化為可供微處理器、傳感器等負載運用的功率。

1958年，電源管理芯片發明(ming)晰集成電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)，一(yi)種稱為芯片(pian)(pian)的電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子元(yuan)件，創始了信號處理和(he)(he)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子的新紀元(yuan)，基(ji)爾比(bi)(bi)因而(er)獲得了2000年的諾貝爾物理學獎。該(gai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)包(bao)括以(yi)下技(ji)術(shu)：精細電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓基(ji)準(zhun)、高性(xing)能、低噪聲運算放大器(qi)、低壓降(jiang)(jiang)通晶體管、低靜態電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流。如電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)需要具(ju)有瞬時校(xiao)準(zhun)和(he)(he)輸出狀態自(zi)檢功用，穩壓器(qi)的壓降(jiang)(jiang)和(he)(he)自(zi)身功耗要求(qiu)低，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)成本低低，方案簡略，那么線(xian)性(xing)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)是(shi)最合適的選擇。電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)管理芯片(pian)(pian)分類(lei)也包(bao)括這些方面，比(bi)(bi)如線(xian)性(xing)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)芯片(pian)(pian)、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓基(ji)準(zhun)芯片(pian)(pian)、開關電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)芯片(pian)(pian)、LCD驅(qu)動芯片(pian)(pian)、LED驅(qu)動芯片(pian)(pian)、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓檢測芯片(pian)(pian)、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)管理芯片(pian)(pian)等(deng)。
