TEA2261集成电路（IC）的ACDC转换器离线开关规格书PDF中文资料

TEA2261属于集成电路（IC）的ACDC转换器离线开关。由意法半导体集团制造生产的TEA2261AC 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 TEA2260/61 is a monolithic integrated circuit for the use in primary part of an off-line switching mode power supply.

All functions required for SMPS control under normal operating, transient or abnormal conditions are provided.

The capability of working according to the “master-slave” concept, or according to the “primary regulation” mode makes the TEA2260/61 very flexible and easy to use. This is particularly true for TV receivers where the IC provides an attractive and low cost solution (no need of stand-by auxiliary power supply). See application note AN376/0490 for detailed information.
