L6598集成電路（IC）的ACDC轉(zhuǎn)換器離線開關規(guī)格書PDF中文資料

L6598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L6598AC 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(gòu)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

The device is manufactured with the BCD OFF LINE technology, able to ensure voltage ratings up to 600V, making it perfectly suited for AC/DC Adapters and wherever a Resonant Topology can be beneficial. The device is intended to drive two Power MOS, in the classical Half Bridge Topology. A dedicated Timing Section allows the designer to set Soft Start Time, Soft Start and Minimum Frequency. An Error Amplifier, together with the two Enable inputs, are made available. In addition, the integrated Bootstrap Diode and the Zener Clamping on low voltage supply, reduces to a minimum the external parts needed in the applications.
