Abstract: An apparatus includes a resonant converter controller having a converter voltage sensing terminal, a reference voltage terminal, a converter current sensing terminal, first and second converter capacitor terminals, and first and second control outputs. The resonant converter controller is configured to: receive a current sensing signal at the converter current sensing terminal; generate a first signal based on the current sensing signal; generate a second signal representing a difference between a first voltage at the converter voltage sensing terminal and a reference voltage at the reference voltage terminal; and generate first and second switching signals at, respectively, the first and second control outputs responsive to the first signal, the second signal, and a capacitor voltage between the first and second converter capacitor terminals to regulate the first voltage based on the reference voltage.
