NCP1252CDR2G規(guī)格書(shū)詳情
NCP1252CDR2G屬于集成電路(IC)的ACDC轉(zhuǎn)換器離線開(kāi)關(guān)。由安森美半導(dǎo)體公司制造生產(chǎn)的NCP1252CDR2GAC 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,但也有許多專門用于此用途的庫(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。
The NCP1252 controller offers everything needed to build cost?
effective and reliable ac?dc switching supplies dedicated to ATX
power supplies. Thanks to the use of an internally fixed timer,
NCP1252 detects an output overload without relying on the auxiliary
Vcc. A Brown?Out input offers protection against low input voltages
and improves the converter safety. Finally a SOIC?8 package saves
PCB space and represents a solution of choice in cost sensitive project.
