VIPER53DIP-E屬于集成電路（IC）的ACDC轉(zhuǎn)換器離線開關(guān)。由意法半導體集團制造生產(chǎn)的VIPER53DIP-EAC DC 轉(zhuǎn)換器，離線開關(guān)該系列是元器件級控制產(chǎn)品，用于構(gòu)建將交流市電轉(zhuǎn)換為直流電（通常電壓大幅降低）的設(shè)備。集成和未集成系統(tǒng)主要開關(guān)元件的器件均包括在內(nèi)。由于高輸入輸出電壓比，以及此類系統(tǒng)中通常需要隔離，這些器件通常與外部變壓器配合使用。盡管通常使用定制變壓器來實現(xiàn)此用途，但也有許多專門用于此用途的庫存產(chǎn)品，請參見“開關(guān)轉(zhuǎn)換器，SMPS 變壓器”標題。

描述 Description

The VIPer53-E 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, with the following benefits:

■ Overload and short circuit controlled by feedback monitoring and delayed device reset.

■ Efficient standby mode by enhanced pulse skipping.

■ Primary regulation or secondary loop failure protection through high gain error amplifier.
