Load-Induced Voltage Overshoot Detection And Correction In Switching Power Supplies

A method for substantially mitigating output voltage overshoot in a switching power supply, the method comprising:

• controlling a switch network of the switching power supply to generate an output voltage;
• detecting an occurrence of an output voltage overshoot condition associated with the output voltage based on switching activity of the switch network;
• and
• controlling the switch network to couple the output to a low supply voltage to correct the output voltage overshoot condition.

A switching power supply system comprising:

• switch means for providing an output voltage to an output load of the switching power supply system;
• means for controlling switching activity of the switch means based on a feedback signal associated with the output voltage;
• and
• means for at least one of detecting and correcting an output voltage overshoot condition caused by a transition in the output load based on the switching activity of the switch means.
