Abstract:
A control circuit controls a switch of a switching current converter receiving an input quantity, with a transformer having a primary winding and a sensor element generating a sensing signal correlated to a current in the primary winding. The control circuit has a comparator stage configured to compare a reference signal with a comparison signal correlated to the sensing signal and generate an opening signal for the switch. The comparator stage has a comparator element and a delay-compensation circuit. The delay-compensation circuit is configured to generate a compensation signal correlated to the input quantity and to a propagation delay with respect to the opening signal. The comparator element generates the opening signal with an advanced timing correlated to the input quantity and to the propagation delay.

Claim (Index 17):
A control method, comprising:\n controlling a switching element of switching converter including the switching element and an inductive element coupled to the switching element; sensing an input quantity supplied to the switching converter; sensing a current in the inductive element; generating a comparison signal based on a difference between a reference the sensed current; generating a drive control signal to control the switching element; providing the drive control signal to open the switching element; detecting switching of the switching element in response to the provided drive control to open the switching element, the switching element having a propagation delay between the drive control signal being provided to open the switching element and an opening of the switching element in response to the provided drive control signal; sensing the propagation delay each switching cycle of the switching current converter; generating a compensation signal based on the input quantity and the sensed propagation delay; and adjusting a timing of the providing of the drive control signal to open the switching element, the timing being based on the input quantity and the sensed propagation delay.
