Classification: CPC H  Y | IPC H

Claim 12:
13. A resonant DC-DC converter control circuitry, comprising:
a first flip-flop configured to generate a first power transistor control signal; and
a second flip-flop configured to generate a second power transistor control signal;
a time-to-voltage converter coupled to the first flip-flop and the second flip-flop, and configured to generate a time voltage proportional to a half cycle of the first power transistor control signal or the second power transistor control signal;
a multiplier coupled to the time-to-voltage converter, and configured to multiply the time voltage with a feedback signal received from an output of a resonant DC-DC converter; and
a differential amplifier coupled to the multiplier, and configured to generate a first threshold voltage and a second threshold voltage based on an output signal of the multiplier.
