Abstract
A drive circuit for a synchronous rectifier, a method of driving a synchronous rectifier and a power converter incorporating the drive circuit or the method. In one embodiment, the drive circuit includes: (1) a first drive circuit stage configured to derive a timing for at least one drive signal from a secondary winding of a transformer coupled to the synchronous rectifier and (2) a second drive circuit stage, coupled to the first drive circuit stage and configured to employ a substantially stable voltage source to provide power for the at least one drive signal and apply the at least one drive signal to at least one control terminal of at least one synchronous rectifier switch in the synchronous rectifier.
