Claim 6:
7. A resonant DC-DC converter control circuitry, comprising:
a differential integrator configured to:
generate a first threshold ramp based on a feedback signal received from an output of a resonant DC-DC converter;
generate a second threshold ramp based on the feedback signal;

a first comparator coupled to the differential integrator, and configured to compare the first threshold ramp to a resonant voltage generated in the resonant DC-DC converter;
a second comparator coupled to the differential integrator, and configured to compare the second threshold ramp to the resonant voltage;
a first flip-flop coupled to the first comparator, and configured to generate a first power transistor control signal based on an output signal of the first comparator;
a second flip-flop coupled to the second comparator, and configured to generate a second power transistor control signal based on an output signal of the second comparator; and
a monostable multivibrator coupled to the first flip-flop and the second flip-flop, and configured to generate a pulse responsive to the first power transistor control signal or the second power transistor control signal.
