VIPER53E集成电路（IC）的ACDC转换器离线开关规格书PDF中文资料

VIPER53E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VIPER53EAC 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。

STATE OF THE ART PRIMARY SIDE SWITCH FOR AC/DC CONVERTERS

The new VIPer53E includes a PWM driver, an MDmesh MOSFET, a start-up high voltage current source and several on-chip protection circuits. The VIPer53E is an alternative choice to the VIPer53 when only the secondary regulation is required in

a power supply. Like the standard VIPer53, the new version is housed in surface mounting DIP-8 and PowerSO-10 packages.
