描述 Description

Off-Line SMPS Current Mode Controller with integrated 800V CoolMOS? and Start up cell (input OVP & frequency jitter) in DIP-7
The ICE3AR4780VJZ is a modified version of ICE3ARxx80JZ (CoolSET?-F3R 800V) in DIP-7 package. It adds in the input OVP feature but removes the brownout feature and external protection enable feature. In summary, the ICE3AR4780VJZ is a device running at 100kHz, implemented with input OVP feature, installed with 800V MOSFET with startup cell and housed in DIP-7 package. It provides good voltage margin of MOSFET, lowest standby power, selectable burst level, reduced output ripple during burst mode, robust protection with input OVP feature, accurate maximum power control for both maximum power and burst power, low EMI with frequency jittering and soft gate drive, built-in and flexible protections, etc.

簡介

ICE3AR4780VJZ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ICE3AR4780VJZAC 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。
