Claim 0:
1. A resonant DC-DC converter control circuitry, comprising:
a feedback input;
a differential integrator including:
a first input coupled to the feedback input;
a second input coupled to a ground terminal;
a first output; and
a second output;

a resonant voltage input;
a first comparator including:
an output;
a first input coupled to the resonant voltage input; and
a second input coupled to the first output of the differential integrator;

a second comparator including:
an output;
a first input coupled to the resonant voltage input; and
a second input coupled to the second output of the differential integrator;

a first flip-flop including an input coupled to the output of the first comparator, and an output;
a second flip-flop including an input coupled to the output of the second comparator, and an output; and
a monostable multivibrator including an input coupled to the output of the first flip-flop and the output of the second flip-flop.
