Abstract
A control method used in a resonant converter with a switching circuit and a resonant circuit, wherein the switching circuit has a high side transistor coupled between an input voltage and a switch node and a low side transistor coupled between the switch node and a reference ground, the resonant circuit is coupled to the switch node and has a resonant capacitor and a resonant inductor. The method includes: generating an output feedback signal based on a signal of the resonant converter; sensing the voltage across the resonant capacitor generating a signal; comparing the output feedback signal with the voltage sensing signal to generate a high side off signal; determining when to turn off the high side transistor and turn on the low side transistor; detecting an on-time of the high side transistor; and determining when to turn off the low side transistor and turn on the high side transistor.
