VIPER17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 rugged power section, a PWM control,two levels of overcurrent protection, overvoltage and overload protections, hysteresisthermal protection, soft-start and safe auto-restart after any fault condition removal.The burst mode operation and the device’s very low consumption meet the standby energysaving regulations.
Advance frequency jittering reduces EMI filter cost. Brown-out function protects theswitch mode power supply when the rectified input voltage level is below the normalminimum level specified for the system. The high voltage startup circuit is embedded inthe device.

特性 Features

• 800 V avalanche rugged power section

• Operating frequency:
• 60 kHz for Ltype
• 115 kHz for H type
• Standby power AC
• Limiting current with adjustable set point
• Adjustable and accurate overvoltage protection
• On-board soft-start
• Safe auto-restart after a fault condition
• Hysteresis thermal shutdown

简介

VIPER17属于集成电路（IC）的ACDC转换器离线开关。由制造生产的VIPER17AC 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。
