Abstract
A power supply protection circuit with surge suppression and a method thereof are provided. The power supply protection circuit used in the power converter includes a discharge circuit and a surge suppression circuit. The surge detection circuit determines whether the discharge conditions are compliant based on the control signal of the low-side switch in the power converter and the output voltage. When the discharge conditions are non-compliant, the surge detection circuit outputs a discharge signal to the discharge circuit, so that the discharge circuit discharges the output voltage. When the discharge conditions are determined to be non-compliant, the surge detection circuit stops outputting the discharge signal to the discharge circuit, so that the discharge circuit stops discharging the output voltage.
