簡(jiǎn)介

NCP103屬于集成電路（IC）的ACDC轉(zhuǎn)換器離線開(kāi)關(guān)。由制造生產(chǎn)的NCP103AC DC 轉(zhuǎn)換器，離線開(kāi)關(guān)該系列是元器件級(jí)控制產(chǎn)品，用于構(gòu)建將交流市電轉(zhuǎn)換為直流電（通常電壓大幅降低）的設(shè)備。集成和未集成系統(tǒng)主要開(kāi)關(guān)元件的器件均包括在內(nèi)。由于高輸入輸出電壓比，以及此類(lèi)系統(tǒng)中通常需要隔離，這些器件通常與外部變壓器配合使用。盡管通常使用定制變壓器來(lái)實(shí)現(xiàn)此用途，但也有許多專(zhuān)門(mén)用于此用途的庫(kù)存產(chǎn)品，請(qǐng)參見(jiàn)“開(kāi)關(guān)轉(zhuǎn)換器，SMPS 變壓器”標(biāo)題。
