ALTAIR04-900集成电路（IC）的ACDC转换器离线开关规格书PDF中文资料

ALTAIR04-900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ALTAIR04-900AC 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 ALTAIR04-900 is a high voltage all-primarysensing switcher, operating directly from the rectified mains with minimum external parts. It combines a high-performance low voltage PWM controller chip and a 900 V avalanche-rugged power section in the same package.
