STR-A6131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

STR-A6131屬于集成電路（IC）的ACDC轉(zhuǎn)換器離線開關(guān)。由三墾電氣株式會社制造生產(chǎn)的STR-A6131AC 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”標題。

General Descriptions

The STR-A6100 series are power ICs for switching power supplies, incorporating a MOSFET and a current

mode PRC controller IC. PRC (Pulse Ratio Control) controls on-time with fixed off-time.

The IC includes a startup circuit and a standby function to achieve the low standby power. The rich set

of protection features helps to realize low component counts, and high performance-to-cost power supply.
