摘要：A power converter includes a voltage conversion unit that provides a first driving voltage at a first output electrode by converting a power supply voltage in response to a first control signal, the voltage conversion unit being configured to provide a second driving voltage at a second output electrode by converting the power supply voltage after a short detection period, the voltage conversion unit being configured to shut down in response to a third control signal, and a short detection unit that generates the third control signal by comparing a magnitude of a voltage of the second output electrode with a magnitude of a reference voltage during the short detection period.
