VIPER50集成電路（IC）的ACDC轉(zhuǎn)換器離線開關規(guī)格書PDF中文資料

VIPER50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VIPER50AC 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

VIPer50?/50A, made using VIPower M0 Technology, combines on the same silicon chip a state-of-the-art PWM circuit together with an optimized high voltage avalanche rugged Vertical Power MOSFET (620V or 700V / 1.5A).

Typical applications cover off line power supplies with a secondary power capability of 25W in wide range condition and 50W in single range or with doubler configuration. It is compatible from both primary or secondary regulation loop despite using around 50 less components when compared with a discrete solution. Burst mode operation is an additional feature of this device, offering the possibility to operate in stand-by mode without extra components.
