1. A method for configuring a switched-mode power converter for operation, the method comprising:
providing to a maximum voltage node as a maximum voltage, a version of the higher of a first voltage on a first node and a second voltage on a second node;
generating a first signal indicating whether to operate the switched-mode power converter in a buck mode of operation or a boost mode of operation based on the first voltage and a first voltage domain defined by the maximum voltage;
generating a second signal indicating whether to operate the switched-mode power converter in the buck mode of operation or the boost mode of operation based on the first voltage and a second voltage domain defined by the first voltage; and
combining the first signal and the second signal to generate a digital configuration indicator signal.
