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 11):
A switching power supply, comprising:\n switching converter circuitry including an inductive element, a switch, and a sensor element configured to generate a sensing signal based on a current in the inductive element, the switching converter configured to receive an input quantity and having a switching cycle; a load coupled to the inductive element; and a control module coupled to the switching converter circuitry, the control module configured to compare a reference signal with a comparison signal that is based on the sensing signal and to generate a switch off signal to turn off the switch, the switch having a propagation delay with respect to the switch off signal and a turning off of the switch, the control module further configured to sense the propagation delay and to estimate a value of the propagation delay each switching cycle of the switching converter, and configured to generate a compensation signal based on the input voltage and the estimated value of the propagation delay in the switching cycle, and further configured to configured to receive the reference signal, the sensing signal, and the compensation signal, and to generate the switching element off signal with an advanced timing based on the input quantity and the estimated value of the propagation delay.
