Abstract
A power converter includes a power conversion circuit converting an input voltage into an output voltage, and a feedback control circuit including a voltage detector module generating a feedback signal having a signal frequency proportional to a magnitude of the output voltage, a phase detector module generating counting-up and counting-down signals based on the signal frequency and a reference frequency, and a control input generator module controlling the power conversion circuit to adjust the output voltage based on the counting-up and counting-down signals. The logic levels of the counting-up and counting-down signals are maintained until a relative relationship between the signal frequency and the reference frequency changes.
