SSC1S311A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

SSC1S311A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(huì)社制造生產(chǎn)的SSC1S311AAC DC 轉(zhuǎn)換器，離線開關(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(shí)現(xiàn)此用途，但也有許多專門用于此用途的庫存產(chǎn)品，請(qǐng)參見“開關(guān)轉(zhuǎn)換器，SMPS 變壓器”標(biāo)題。

Description

SSC1S311A is the controller IC of a quasi-resonant mode for a switching power supplies. The IC incorporates a startup circuit and a standby function to reduce a power consumption and standby power. In normal operation, the quasi-resonant mode operation achieves high efficiency and low noise. In addition, in medium to low load conditions, the operation mode is automatically changes the quasi-resonant mode to the bottom-skip mode to improve efficiency. The IC is provided in the SOIC8 package. The power supply that is a low component counts and a high performance-tocost can be achieved by the rich set of protection features.
