POWER SUPPLY ARRANGEMENT FOR AN ELECTRONIC DEVICE

摘要

The invention relates to a power supply arrangement (10) for an electronic device, comprising a first switching converter (11) having a first regulating circuit (16) for providing a regulated output voltage (DC-out) to a node point (18) and a second switch converter (12) having a second regulating circuit (17) for alternatively providing the regulated output voltage (DC-out) to the node point (18). The power supply arrangement (10) furthermore comprises a control circuit connected to the first regulating circuit (16) and the second regulating circuit (17). The control circuit is configured to hold an existing regulating state of the first regulating circuit (16) upon a switching of the power supply from the first switching converter (11) to the second switching converter (12) and to deactivate the first switching converter (11) and, upon switching the power supply from the second switch converter (12) to the first switch converter (11), to reactivate the first switch converter (11) using the held regulating state.
