Abstract
A supply circuit comprises a regulated positive supply circuit and an unregulated negative supply circuit. The regulated positive supply circuit includes an inductor arranged to receive input energy from an input circuit node, a switch circuit coupled to the inductor at a switch circuit node, and a control circuit coupled to the switch circuit. The control circuit is configured to control activation of the switch circuit to regulate a voltage at a regulated circuit node and generate a positive output voltage at a positive output circuit node. The unregulated negative supply circuit is operatively coupled to the switch circuit node and is configured to generate a negative supply voltage at a negative output circuit node.
