1. A system, comprising:
a battery configured to provide an input voltage;
a switching converter coupled to the battery, wherein the switching converter includes a power switch;
a control circuit coupled to the power switch, wherein the control circuit includes:
a switch driver circuit coupled to the power switch;
a comparator having a comparator output and first and second comparator inputs, wherein the comparator is configured to provide a first control signal at the comparator output to initiate turning the power switch on; and
