description A synchronous rectifier driver circuit is configured to drive a synchronous rectifier FET and includes a first terminal configured to be connected to a source terminal of the synchronous rectifier FET. A second terminal is configured to be connected to a drain terminal of the synchronous rectifier FET, and a third terminal is configured to be connected to a gate terminal of the synchronous rectifier FET. The synchronous rectifier driver circuit is configured to measure the voltage between the second terminal and the first terminal, and detect a switch-on instant in which the measured voltage reaches a first threshold value and a switch-off instant in which the measured voltage reaches a second threshold value. The synchronous rectifier driver circuit generates a drive signal between the third terminal and the first terminal as a function of the measured voltage.
