Abstract
A circuit for driving a synchronous rectifier may include a voltage level detecting unit detecting a voltage level of the synchronous rectifier; an on/off signal generating unit generating an on signal controlling the synchronous rectifier to be turned on when the voltage level detected by the voltage level detecting unit is decreased to a voltage level equal to or less than a preset reference voltage level, and generating an off signal controlling the synchronous rectifier to be turned off when the voltage level detected by the voltage level detecting unit is increased to a voltage level exceeding the reference voltage level; a minimum time determining unit controlling the synchronous rectifier to be turned on during a preset first period; and a blanking time determining unit controlling the synchronous rectifier so as not to be turned on during a preset second period after the synchronous rectifier has been turned off.
