Abstract: In one example, an NFC controller includes a first node configured to be coupled to a battery and a second node configured to receive a regulated voltage from an external dc/dc converter coupled to the first node. A third node is configured to be coupled to a radio frequency output of the NFC controller. The third node is configured to be coupled to either the first node or the second node in a first mode, and to either to the first node or to first and second nodes in a second mode.
