NCP1230D100R2G集成电路（IC）的ACDC转换器离线开关规格书PDF中文资料

NCP1230D100R2G属于集成电路（IC）的ACDC转换器离线开关。由安森美半导体公司制造生产的NCP1230D100R2GAC 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。

The NCP1230 represents a major leap towards achieving low standby power in medium-to-high power Switched-Mode Power Supplies such as notebook adapters, off-line battery chargers and consumer electronics equipment. Housed in a compact 8-pin package (SOIC-8, SOIC-7, or PDIP-7), the NCP1230 contains all needed control functionality to build a rugged and efficient power supply.
