Abstract
A power converter which converts between a first current at a first voltage provided at a first node and a second current at a second voltage provided at a second node. The power converter has a flying capacitor, an inductor and five switches. Furthermore, the power converter has a control unit to control four switches during steady state operation within a sequence of different operations states, in order to set the second voltage or the second current to a target level. In addition, the control unit detects the occurrence of a load transient at the second node, and in reaction to detecting occurrence of a load transient, to at least partially close a bypass switch, in order to provide additional current from the flying capacitor to the second node or in order to divert current from the inductor towards the reference potential.
