Abstract
A conversion control circuit for controlling a resonant power converter which includes a high-side and a low-side transistor which are coupled to convert an input voltage into an output voltage, and a resonant circuit including at least one resonant inductor and a resonant capacitor. The conversion control circuit includes: a sensing circuit for sensing a resonant-related parameter related to the resonance produced by the resonant circuit to generate a sensed signal; and a PWM control circuit for generating a high-side and a low-side driving signal according to the sensed signal and a feedback signal related to the output voltage. When the feedback signal falls below a low-power threshold, the resonant power converter enters a burst OFF period, during which both the high-side and the low-side transistors are turned OFF. A lower limit of the burst OFF period is equal to a switching period of the high-side and the low-side driving signals.
