ICE2QR2280G集成電路（IC）的ACDC轉(zhuǎn)換器離線開關(guān)規(guī)格書PDF中文資料

ICE2QR2280G屬于集成電路（IC）的ACDC轉(zhuǎn)換器離線開關(guān)。由英飛凌科技股份公司制造生產(chǎn)的ICE2QR2280GAC DC 轉(zhuǎn)換器，離線開關(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(qǐng)參見“開關(guān)轉(zhuǎn)換器，SMPS 變壓器”標(biāo)題。

Description

The CoolSETTM-Q1 series (ICE2QRxx80G) is the first generation of quasi-resonant integrated power ICs. It is optimized for off-line switch mode power supply applications such as LCD monitor, DVD R/W, DVD Combo, Blue-ray DVD, set top box, etc. Operating the MOSFET switch in quasi-resonant mode, lower EMI, higher efficiency and lower voltage stress on secondary diodes are expected for the SMPS. Based on the BiCMOS technology, the CoolSETTM-Q1 series has a wide operation range (up to 25 V) of IC power supply and lower power consumption. It also offers many advantages such as a quasi-resonant operation till very low load increasing the average system efficiency compared to the other conventional solutions; the Active Burst Mode operation enables an ultra-low power consumption at standby mode with small and a controllable output voltage ripple.
