摘要： An adaptive over-voltage protection circuit includes an over-voltage protection reference voltage provider and an over-voltage signal output unit. The over-voltage protection reference voltage provider provides a voltage of an over-voltage protection level higher than that of an over-voltage protection voltage corresponding to an output voltage supplied to a load from among a plurality of different over-voltage protection levels as an over-voltage protection reference voltage when the output voltage reaches a range of a rated voltage of the load. The over-voltage signal output unit outputs an over-voltage signal indicating an over-voltage by comparing the over-voltage protection voltage with the over-voltage protection reference voltage.
