ICE5QSAG集成电路（IC）的ACDC转换器离线开关规格书PDF中文资料

ICE5QSAG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ICE5QSAGAC 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。

描述 Description

The Quasi-Resonant, ICE5QSAG is the 5th generation of quasiresonant controller optimized for off-line switch power supply in cascode configuration. The improved digital frequency reduction with proprietary novel Quasi-Resonant operation offers lower EMI and higher efficiency for wide AC range by reducing the switching frequency difference between low and high line. The enhanced active burst mode enables flexibility in standby power range selection. The product has a wide operating range (10~25.5 V) of IC power supply and lower power consumption. The numerous protection functions including the robust line protection (both input OVP and brownout) to support the protections of the power supply system in failure situations. All of these make the ICE5QSAG an outstanding controller for Quasi-Resonant flyback converter in the market.
