Abstract
A power converter improving input overvoltage from output voltage drop is provided. The power converter includes a high-side switch, a low-side switch, a control circuit, a voltage threshold determining circuit and a voltage drop suppression circuit. The voltage threshold determining circuit determines whether or not an output voltage of the power converter is dropping to determine or adjust a voltage threshold. The voltage drop suppression circuit detects a voltage of a first terminal of the high-side switch. When the voltage drop suppression circuit determines that the detected voltage of the first terminal of the high-side switch is higher than the voltage threshold, the voltage drop suppression circuit pulls down the voltage of the first terminal of the high-side switch.
