STR-W6251D集成電路（IC）的ACDC轉(zhuǎn)換器離線(xiàn)開(kāi)關(guān)規(guī)格書(shū)PDF中文資料

STR-W6251D屬于集成電路（IC）的ACDC轉(zhuǎn)換器離線(xiàn)開(kāi)關(guān)。由三墾電氣株式會(huì)社制造生產(chǎn)的STR-W6251DAC DC 轉(zhuǎn)換器，離線(xiàn)開(kāi)關(guān)該系列是元器件級(jí)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(kāi)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(lèi)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(lái)實(shí)現(xiàn)此用途，但也有許多專(zhuān)門(mén)用于此用途的庫(kù)存產(chǎn)品，請(qǐng)參見(jiàn)“開(kāi)關(guān)轉(zhuǎn)換器，SMPS 變壓器”標(biāo)題。

? Overcurrent protection (OCP) with ac input voltage

compensation function; no additional peripheral circuits

required—minimizes dependency of OCP on ac input

? Overload protection (OLP) with integrated timer reduces

power stress (temperature rise) at overload condition,

requires no peripheral components

? Avalanche-guaranteed MOSFET improves device

capability of withstanding excess surge voltage,

providing a simple surge absorber circuit without

breakdown voltage derating

? Start-up circuit eliminates the need for a start-up resistor,

and helps to reduce input power consumption
