ALTAIR05T-800中文资料离线全初级感应开关稳压器数据手册ST规格书

描述 Description

The ALTAIR05T-800 is a high-voltage all-primary sensing switcher intended to operate directly from the rectified mains with minimum external parts. It combines a low voltage, high performance PWM controller chip and an 800 V avalanche rugged power section in the same package.

特性 Features

• Constant voltage and constant current output regulation (CV/CC) with no optocoupler
• Tight regulation also during heavy load transients
• 800 V avalanche rugged internal power section
• Quasi-resonant (QR) operation
• Low standby power consumption
• Automatic self-supply
• Input-voltage feedforward for mains-independent CC regulation
• Output cable drop compensation
• SO16N package

简介

ALTAIR05T-800属于集成电路（IC）的ACDC转换器离线开关。由ST制造生产的ALTAIR05T-800AC 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。
