描述 Description

ICE3AR4780CJZ CoolSET? is an Off-Line SMPS Current Mode Controller with integrated 800V CoolMOS? and Start-up cell (brownout & CCM) in DIP-7. The major new features include slope compensation for CCM operation and fast AC reset after latch enabled. The major enhanced features include fixed voltage brownout detect and voltage detect for the burst selection. It's the ideal solution for low power SMPS applications.? Evaluation Board for this product is available.

簡介

ICE3AR4780CJZ屬于集成電路（IC）的ACDC轉(zhuǎn)換器離線開關(guān)。由制造生產(chǎn)的ICE3AR4780CJZAC DC 轉(zhuǎn)換器，離線開關(guān)該系列是元器件級控制產(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實(shí)現(xiàn)此用途，但也有許多專門用于此用途的庫存產(chǎn)品，請參見“開關(guān)轉(zhuǎn)換器，SMPS 變壓器”標(biāo)題。
