ICE2QR4765Z集成電路（IC）的ACDC轉換器離線開關規(guī)格書PDF中文資料

ICE2QR4765Z屬于集成電路（IC）的ACDC轉換器離線開關。由英飛凌科技股份公司制造生產的ICE2QR4765ZAC DC 轉換器，離線開關該系列是元器件級控制產品，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。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品，請參見“開關轉換器，SMPS 變壓器”標題。

Description

The CoolSET? -Q1 series (ICE2QRxx65Z) 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 CoolSET? -Q1 series has awide operation range (up to 25V) of IC power supply and lower power consumption. It also offers many advantages such as quasi-resonant operation till very low load which increases the average system efficiency,

Active Burst Mode operation which enables an ultra-low power consumption at standby mode with small and controllable output voltage ripple, etc.
