描述 Description

Integrated power management IC with 650V avalanche rugged CoolMOS?, startup cell and QR current mode flyback PWM controller in DSO-16/12 packageCapable for 38W SMPS design. The quasi QR CoolSET? series continues to deliver design agility and miniaturization. Upon the successful F3 CoolSET?, this new series offer the possibility of higher efficiency and better EMI performance. The digital frequency reduction feature score a very stable operation with decreasing load change, and the fold-back correction keep the maximum power limits within tolerance desired by SMPS designers. The active burst mode operation during low power consumption, remains market leaders in providing best-in-class power consumption during standby.

簡介

ICE2QR0665G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ICE2QR0665GAC 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。
