Abstract

Disclosed is a power converter which achieves a high efficiency. The power converter comprises: a first power converting unit which converts a first voltage to a second voltage; and a second power converting unit which is connected with the first power converting unit and converts the second voltage to a third voltage. Here, the second power converting unit includes a first transistor and a second transistor which are connected in parallel with each other with respect to an output node of the second power converting unit, wherein, when in a charging mode or discharging mode, the second transistor is turned-on only during a part of an ON period of the first transistor.
