VIPER16数据手册集成电路（IC）的ACDC转换器离线开关规格书PDF

描述 Description

The device is an off-line converter with an 800 V avalanche ruggedness power section, a PWM controller, user defined overcurrent limit, protection against feedback network disconnection, hysteretic thermal protection, soft start up and safe auto restart after any fault condition. It is able to power itself directly from the rectified mains, eliminating the need for an auxiliary bias winding. Advance frequency jittering reduces EMI filter cost. Burst mode operation and the devices very low consumption both help to meet the standard set by energy saving regulations.

特性 Features

• 800 V avalanche rugged power section
• PWM operation with frequency jittering for low EMI
• Operating frequency:
•60 kHz for L type
•115 kHz for H type
• No need of auxiliary winding for low power application
• Standby power

简介

VIPER16属于集成电路（IC）的ACDC转换器离线开关。由制造生产的VIPER16AC 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。
