VIPER53EDIP集成電路（IC）的ACDC轉(zhuǎn)換器離線開關(guān)規(guī)格書PDF中文資料

VIPER53EDIP屬于集成電路（IC）的ACDC轉(zhuǎn)換器離線開關(guān)。由意法半導(dǎo)體集團制造生產(chǎn)的VIPER53EDIPAC 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(biāo)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.

Features

Automatic burst mode for very low consumption in stand-by conditions (less than 500mW);

Integrated high voltage start-up current source;

Overload and short circuit control;

Over-voltage protection at 18V;

Over-temperature shutdown;

Under-voltage protection;

Current mode control with adjustable drain current limitation;

Externally set switching frequency, up to 300kHz.
