VIPER53ESP-E集成电路（IC）的ACDC转换器离线开关规格书PDF中文资料

VIPER53ESP-E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VIPER53ESP-EAC 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 VIPer53E combines an enhanced current mode PWM controller with a high voltage MDMesh Power MOSFET in the same package. Typical applications cover offline power supplies with a secondary power capability ranging up to 30W in wide range input voltage, or 50W in single European voltage range and DIP-8 package and 40W in wide range input voltage, or 65W in single European voltage range and PowerSO-10 package, with the following benefits:

– Overload and short-circuit events controlled by feedback monitoring and delayed device reset;

– Efficient standby mode by enhanced pulse skipping.

– Integrated start-up current source is disabled during normal operation to reduce the input power.
