Abstract:
An overvoltage protection circuit configured to prevent an overvoltage of an output voltage of a switching converter, can include: an output voltage simulation circuit configured to generate an output voltage simulation signal according to circuit parameters of the switching converter, where the output voltage simulation signal changes along with the output voltage; and an overvoltage signal generator configured to activate an overvoltage signal when a feedback voltage is less than a first threshold value and the output voltage simulation signal is greater than a second threshold value.
