VIPER122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 a high performance high voltage converter that combines a 730 V rugged power MOSFET with PWM control. The device embeds high voltage startup and current sense circuitry, which helps reduce the number of components in a BoM. Frequency jittering spreads the EMI and allows the use of a smaller filter. The burst mode feature provides very low input power consumption at light loads.

特性 Features

• 730 V avalanche rugged power MOSFET
• PWM controller
• 3.3 V reference voltage
• Frequency jittering
• 40 mW no load input power at 230 VAC
• Short-circuit protection
• Thermal shutdown

简介

VIPER122属于集成电路（IC）的ACDC转换器离线开关。由制造生产的VIPER122AC 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。
