TOP227集成电路（IC）的ACDC转换器离线开关规格书PDF中文资料

TOP227属于集成电路（IC）的ACDC转换器离线开关。由荷兰帕沃英蒂格盛有限公司制造生产的TOP227AC 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 second generation TOPSwitch™-II family is more cost

effective and provides several enhancements over the first

generation TOPSwitch family. The TOPSwitch-II family

extends the power range from 100W to 150W for 100/115/

230 VAC input and from 50W to 90W for 85-265 VAC universal

input. This brings TOPSwitch technology advantages

to many new applications, i.e. TV, Monitor, Audio amplifiers,

etc. Many significant circuit enhancements that reduce the

sensitivity to board layout and line transients now make the

design even easier. The standard 8L PDIP package option
