DRIVER DEVICE OF SYNCHRONOUS RECTIFIER

摘要

According to an embodiment of the present invention, a device for driving a synchronous rectifier comprises: a voltage detecting unit which is formed on a power input terminal to detect a voltage inputted through the power input terminal; an adjusting unit to receive the voltage detected by the voltage detecting unit and to adjust and output the received voltage; and a comparing unit to receive a voltage value adjusted by the adjusting unit by a positive terminal (+), to receive a synchronous rectification initiation value by a negative terminal (-), and to output an instruction value of the synchronous rectifier according to comparison of the received voltage value and synchronous rectification initiation value, thereby driving the synchronous rectifier at a consistent output current.
