Abstract
An electronic apparatus includes: a converter including a switching device, an inductor, and an output capacitor; a protection switching device provided between the inductor and the output capacitor; and a protection circuit configured to provide a control voltage to: turn on the protection switching device based on a first voltage applied between the inductor and the protection switching device, the first voltage being lower than or equal to a threshold level corresponding overvoltage, and turn off the protection switching device based on the first voltage, the first voltage being higher than the threshold level. The control voltage is varied depending on variation in the input voltage or the output voltage and having a level corresponding to a threshold voltage for turning on or off the protection switching device.
