Abstract
A driver circuit for synchronous rectifier electronic switches, such as SR MOSFETs in resonant converters controls a pair of synchronous rectifier electronic switches to apply thereto a drive voltage to switch the synchronous rectifier electronic switches on and off synchronously with a converter current. The driver circuit includes a programming module to produce a first signal indicative of the figure of merit of the synchronous rectifier electronic switches, and, optionally, a current sensing module to produce a second signal indicative of the output current of the synchronous rectifier electronic switches. An output module is included to generate a value for the drive voltage which is a function of the first signal indicative of the figure of merit and, optionally, of the second signal indicative of the output current of the synchronous rectifier electronic switches.
