1. A dual-polarity multi-output synchronous boost converter comprising:

  • an inductor;

    first, second, third, fourth and fifth output nodes; and

    a switching network, the switching network being configured to provide a first mode of circuit operation in which a positive electrode of the inductor is connected to an input voltage and a negative electrode of the inductor is connected to ground, a second mode of circuit operation in which the negative electrode of the inductor is connected in sequence to each of the first, second and third output nodes and the positive electrode of the inductor is connected in sequence to each of the fourth and fifth output nodes, and a third mode of circuit operation in which the positive electrode of the inductor is connected to the input voltage and the negative electrode of the inductor is connected in sequence to each of the first, second and third output nodes.
