1. A circuit, comprising:
a resistor divider circuit coupled between an input terminal and a ground terminal, the resistor divider circuit having divider outputs;
a switch circuit having a switch circuit output, switch circuit inputs, and switch control terminals, the switch circuit inputs coupled to the divider outputs;
a comparator having a first input coupled to a voltage reference, a second input coupled to the switch circuit output, and a comparator output; and
a control circuit having a control input, switch control outputs, and a current control output, the control input coupled to the comparator output, the switch control outputs coupled to the switch control terminals, and the control circuit configured to, responsive to a state of the comparator output:
set respective states of the switch control output; and
provide a control signal representing a power converter reference current at the current control output responsive to a state of the comparator output.
