Abstract
A method of controlling an isolated switching converter having an output voltage that is adjustable, can include: sampling an output voltage of the isolated switching converter; setting an overvoltage protection threshold corresponding to the output voltage of the isolated switching converter when the isolated switching converter enters a protection mode; and triggering the overvoltage protection by comparing an output voltage feedback signal representing the output voltage against the overvoltage protection threshold.
