VIPER114LSTR集成電路（IC）的ACDC轉換器離線開關規(guī)格書PDF中文資料

VIPER114LSTR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(chǎn)的VIPER114LSTRAC DC 轉換器，離線開關該系列是元器件級控制產(chǎn)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(chǎn)品，請參見“開關轉換器，SMPS 變壓器”標題。

Description

The device is a high voltage converter smartly

integrating an 800 V avalanche-rugged power

MOSFET with PWM current mode control. The

power MOSFET with 800 V breakdown voltage

allows the extended input voltage range to be

applied, as well as the size of the DRAIN snubber

circuit to be reduced. This IC meets the most

stringent energy-saving standards as it has very

low consumption and operates in pulse frequency

modulation under light load. The design of

flyback, buck and buck boost converters is

supported. The integrated HV startup, senseFET, error amplifier and oscillator with jitter allow

a complete application to be designed with the

minimum number of components.

Features
