Abstract
A method operates a switch controller of a power switch. The method includes determining a compensation value based on a quarter period of a resonant cycle of a drain voltage and a propagation delay time, the drain voltage being a voltage at a drain of the power switch, generating a sensing signal based on detection of a valley point of the drain voltage, and generating a control signal for controlling the power switch based on the sensing signal and the compensation value to turn on the power switch at a time corresponding to the valley point of the drain voltage.
