Pulsed feedback switching converter

A method, comprising:

• comparing a measured value signal representative of a an output electrical quantity of a power stage of a switching converter to a reference value;
• producing a digital detection signal based on the comparison of the measured value signal and the reference value;
• performing a corrective action at a control actuator when the measured value signal has a value greater than the reference value, performing the corrective action including:
• receiving the digital detection signal at an input of the control actuator;
• producing a correction signal based on the digital detection signal;
• averaging the correction signal to produce a control voltage signal;
• and
• driving the power stage of the switching convert based on the control voltage signal to regulate the output voltage.

A switching converter, comprising:

• a power stage, including:
• a transformer coupled to an input voltage and configured to produce an output electrical quantity;
• a first switch coupled to the transformer;
• a sensing circuit configured to produce a measured value signal representative of the output voltage of the transformer;
• a signal conditioning circuit, including:
• a comparator configured to receive a reference signal and the measured value signal, and to produce a digital detection signal based on a comparison of the measured value signal and the reference signal;
• a control actuator configured to produce a correction signal based on the digital detection signal;
• an averaging circuit configured to produce a control voltage signal by averaging the correction signal over time;
• a modulator coupled to the signal conditioning circuit and configured to produce a pulsed signal based on the control voltage signal;
• and
• a driver coupled to the modulator and configured to provide a driving signal to the switch of the power stage based on the pulsed signal to regulate the output voltage of the transformer.
