Abstract
A resonant converter controller circuit is provided. Each period in drive control has a drive time interval and a pause time interval for driving/pausing the resonant converter. The resonant converter controller circuit includes a first oscillating means for generating a clock signal, a second oscillating means for generating a sawtooth wave signal, a third oscillating means for generating a rectangular wave signal, comparison means for outputting a comparison signal indication the rive time interval, by comparing the sawtooth wave signal with a threshold signal, which is generated based on a difference voltage between an output voltage of the resonant converter and a target voltage, and which indicates a ration of the drive time interval to the pause time interval, and a logical operation means for generating a drive control signal based on the comparison signal and the rectangular wave signal to drive and control the resonant converter.
