ICE2AS01集成电路（IC）的ACDC转换器离线开关规格书PDF中文资料

ICE2AS01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ICE2AS01AC 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

This stand alone controller provides several special enhancements to satisfy the needs for low power standby and protection features. In standby mode frequency reduction is used to lower the power consumption and provide a stable output voltage in this mode. The frequency

reduction is limited to 20kHz / 21.5 kHz (typ.) to avoid audible noise. In case of failure modes like open loop, overvoltage or overload due to short circuit the device switches in Auto Restart Mode which is controlled by the internal protection unit. By means of the internal precise peak current limitation the dimension of the transformer and the secondary diode can be lower which leads to more cost efficiency.
