MP6973集成電路（IC）的OR控制器理想二極管規(guī)格書(shū)PDF中文資料

MP6973屬于集成電路（IC）的OR控制器理想二極管。由美國(guó)芯源系統(tǒng)有限公司制造生產(chǎn)的MP6973OR 控制器，理想二極管理想二極管控制器也稱(chēng)為 OR-ing 控制器，可用于以?xún)H允許單向電流的方式控制外部通道晶體管（通常為 FET），類(lèi)似于整流二極管，但傳導(dǎo)損耗低得多。在其他應(yīng)用中，它們通常用于在為了冗余和增加電流輸出能力而并行連接的電源中提供逆流保護(hù)。

DESCRIPTION

The MP6973 is a fast turn-off, intelligent rectifier

for flyback converters that integrates a

100V/14mΩ MOSFET. It can replace a diode

rectifier for higher efficiency and power density.

The chip regulates the forward voltage drop of

the internal power switch to VFWD (40mV) and

turns off before the drain-source voltage

reverses.

The MP6973 is optimized for low-side

rectification. The internal ringing detection

circuitry prevents the MP6973 from falsely

turning on during discontinuous conduction

mode (DCM) or quasi-resonant operations.

The MP6973 is available in an SOIC-8 package.
