VIPER53E集成電路（IC）的ACDC轉換器離線開關規(guī)格書PDF中文資料

VIPER53E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VIPER53EAC 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(tǒng)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(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品，請參見“開關轉換器，SMPS 變壓器”標題。

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.
