1. A system, comprising:
a switching voltage converter including a first field effect transistor (FET) and a second FET, the switching voltage converter configured to receive an input voltage and provide an output voltage;
a voltage to current converter coupled between the switching voltage converter and an oscillator, wherein the voltage to current converter is configured to receive an error voltage responsive to the output voltage and provide an oscillator current to the oscillator; and
a comparator coupled to the oscillator and configured to compare the oscillator current to a reference current, wherein an output of the comparator is configured to skip a pulse of an oscillator output responsive to the oscillator current being less than the reference current.
