1. A device comprising:

  • a switched power converter comprising;

    a first converter circuit comprising an output terminal;

    a second converter circuit comprising an input terminal; and

    an inductor configured to connect the output terminal of the first converter circuit to the input terminal of the second converter circuit; and

    a current sensing circuit configured to measure a voltage at a sense input, the sense input of the current sense circuit connected to a first sense terminal via a first diode and connected to a second sense terminal via a second diode, whereinthe first sense terminal is connected to the output terminal of the first converter circuit, andthe second sense terminal is connected to the input terminal of the second converter circuit.
