1. A power device temperature monitor, comprising:

  • an amplifier coupled to at least one of a plurality of inductors of the power device;

    an analog-to-digital converter coupled to an output of the amplifier coupled to the at least one of a plurality of inductors of the power device; and

    a computing device that receives an output of the analog-to-digital converter, the computing device configured to derive a temperature of the power device based on a comparison of a value associated with a voltage drop across the at least one of a plurality of inductors with characterization data that is accessed by the computing device.
