Synchronous rectification technology Introduction:
Synchronous rectification is the use of special low-resistance power MOSFET, a rectifier diode instead of a new technology to reduce rectifier losses. It can greatly improve the efficiency DC / DC converter and the absence of the Schottky barrier voltage caused by the dead zone voltage. Power MOSFET are voltage controlled devices, which in turns voltage characteristics of a linear relationship. When done with the power MOSFET rectifier requires a gate voltage must be rectified voltage phase synchronized to complete the rectification, it is known as synchronous rectification. Synchronous rectification is greatly reduced power output rectifier switching losses, thereby improving the conversion efficiency, reducing power itself fever.
Module Properties: non-isolated step-down module (BUCK) synchronous rectifier
