ICE2QR2280G集成电路（IC）的ACDC转换器离线开关规格书PDF中文资料

ICE2QR2280G属于集成电路（IC）的ACDC转换器离线开关。由英飞凌科技股份公司制造生产的ICE2QR2280GAC DC 转换器，离线开关该系列是元器件级控制产品，用于构建将交流市电转换为直流电（通常电压大幅降低）的设备。集成和未集成系统主要开关元件的器件均包括在内。由于高输入输出电压比，以及此类系统中通常需要隔离，这些器件通常与外部变压器配合使用。尽管通常使用定制变压器来实现此用途，但也有许多专门用于此用途的库存产品，请参见“开关转换器，SMPS 变压器”标题。

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.
