1. A switched-mode power supply, comprising:
a first node;
a second node configured to receive a DC input voltage;
a third node configured to receive a reference voltage;
a first switching transistor and a second switching transistor, the first switching transistor configured to carry current from the second node to the first node, the second switching transistor configured to carry current from the second node to the reference voltage;
a first circuit configured to control the first switching transistor; and
a second circuit configured to control the second switching transistor, wherein the switched-mode power supply is configured to deliver an output voltage at the first node from the DC input voltage, and wherein the first and second circuits are configured to be powered from the output voltage.
