描述 Description

State-of-the-art Quasi Resonance current mode flyback PWM power control IC for power ranges up to 300 W. With innovative protection features for superior safety and reliability in operation. Of special note are its frequency modulation, its ultra low standby power consumption and an extensive array of protection features, allowing low EMI and highly efficient, reliable and cost effective designs. Without startup cell , it is good for main converter where the auxiliary power is provided. It has implemented with extra protection features such as brownout, adjustable blanking time for OLP,etc to suit for system requiremen

特性 Features

簡介

ICE2QS02G屬于集成電路（IC）的ACDC轉換器離線開關。由制造生產(chǎn)的ICE2QS02GAC DC 轉換器，離線開關該系列是元器件級控制產(chǎn)品，用于構建將交流市電轉換為直流電（通常電壓大幅降低）的設備。集成和未集成系統(tǒng)主要開關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“開關轉換器，SMPS 變壓器”標題。
