Abstract:
A control device for a rectifier of a switching converter, the converter powered by an input voltage and suitable for providing an output current. The rectifier is suitable for rectifying an output current of the converter and includes at least one transistor. The control device is suitable for driving the at least one transistor. The control device has a first circuit suitable for identifying the start and the end of every converter switching half-cycle and measuring the duration thereof, a second circuit suitable for generating a signal for turning on the transistor after a given number of measured converter switching half-cycles and when the output current of the converter becomes greater than a reference current.
