  • Controller for controlling a resonant converter
    Patent number: 11689108
    Abstract: A controller includes a first sensing pin receiving a first sensing signal indicating a level of an input voltage of a resonant converter, a second sensing pin receiving a second sensing signal indicating a level of an input current of the resonant converter, a feedback pin receiving a feedback signal indicating a level of an output voltage of the resonant converter, and a first driving pin and a second driving pin controlling a high side switch and a low side switch of the resonant converter, respectively. The controller generates a compensated signal based on the first sensing signal, compares the compensated signal with a peak value of the second sensing signal to generate a first comparison result, compares the feedback signal with a threshold to generate a second comparison result, and controls the high side low side switches based on the first and the second comparison results.
