1. A switching power converter system that is operable in a boost mode in which a power signal flows in a power signal path from an input node to an output node to provide a stepped-up power signal at the output node, the power converter system comprising:
a switching circuit coupled to the input node;
a first inductor coupled between a first terminal of the switching circuit and the output node;
a second inductor coupled between a second terminal of the switching circuit and a reference node;
a control circuit configured to provide switch control signals to respective switches in the switching circuit to configure the converter system to operate in the boost mode; and
a current signal sensor comprising a resistor coupled between the output node and the control circuit, the current signal sensor configured to monitor a current output at the output node, wherein the control circuit is configured to provide the switch control signals based in part on the current output at the output node.
