SSC3S927L集成電路（IC）的ACDC轉(zhuǎn)換器離線開(kāi)關(guān)規(guī)格書(shū)PDF中文資料

SSC3S927L屬于集成電路（IC）的ACDC轉(zhuǎn)換器離線開(kāi)關(guān)。由三墾電氣株式會(huì)社制造生產(chǎn)的SSC3S927LAC DC 轉(zhuǎn)換器，離線開(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，但也有許多專門用于此用途的庫(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。

Description

The SSC3S927L is a controller with SMZ* method

for LLC current resonant switching power supplies,

incorporating a floating drive circuit for a high-side

power MOSFET. The IC includes useful functions such

as Standby Function, Automatic Dead Time Adjustment,

and Capacitive Mode Detection. The IC achieves high

efficiency, low noise and high cost-effective power

supply systems with few external components.

*SMZ: Soft-switched Multi-resonant Zero Current

switch, achieved soft switching operation during all

switching periods.
