VIPER267KDTR集成電路（IC）的ACDC轉(zhuǎn)換器離線開關規(guī)格書PDF中文資料

VIPER267KDTR屬于集成電路（IC）的ACDC轉(zhuǎn)換器離線開關。由意法半導體集團制造生產(chǎn)的VIPER267KDTRAC DC 轉(zhuǎn)換器，離線開關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）的設備。集成和未集成系統(tǒng)主要開關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“開關轉(zhuǎn)換器，SMPS 變壓器”標題。

Description

The device is a high voltage converter smartly

integrating a 1050 V avalanche-rugged power

section, with a PWM current mode control. The

1050 V-BV power MOSFET allows to extend input

voltage range, and reduce the size of the DRAIN

snubber circuit. This IC meets the most stringent

energy-saving standards as it has very low

consumption and operates in burst mode under

light load.

The integrated HV startup, sense-FET, error

amplifier and oscillator with jitter allow a complete

application to be designed with the minimum

number of components.

The VIPer26K supports the most common SMPS

topologies such as: isolated flyback with

optocoupler, primary-side regulation, non-isolated

flyback with resistive feedback, buck, and buck

boost.
