VIPER53DIP-E集成電路（IC）的ACDC轉換器離線開關規(guī)格書PDF中文資料

VIPER53DIP-E屬于集成電路（IC）的ACDC轉換器離線開關。由意法半導體集團制造生產的VIPER53DIP-EAC DC 轉換器，離線開關該系列是元器件級控制產品，用于構建將交流市電轉換為直流電（通常電壓大幅降低）的設備。集成和未集成系統主要開關元件的器件均包括在內。由于高輸入輸出電壓比，以及此類系統中通常需要隔離，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此用途，但也有許多專門用于此用途的庫存產品，請參見“開關轉換器，SMPS 變壓器”標題。

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.

Features

■ Switching frequency up to 300kHz

■ Current limitation

■ Current mode control with adjustable limitation

■ Soft start and shut-down control

■ Automatic burst mode in standby condition (“Blue Angel“ compliant )

■ Undervoltage lockoutwith Hysteresis

■ HIgh voltage star-tup current source

■ Overtemperature protection

■ Overload and short-circuit control
