Abstract
A circuit and method for controlling a power converter having a high-side and a low-side switch are provided. The circuit may include a comparator configured to receive a reference voltage at a first input and a ramp voltage at a second output, and to output a delay signal based on a comparison of the reference voltage and the ramp voltage. The delay signal may be configured to turn on one or more of the high-side switch and the low-side switch. The circuit may increase or decrease the reference voltage based on a dead time, which equals an amount of time when the high-side switch and the low-side switch are turned off. The circuit may include a first switch that is controlled to lower the reference voltage if a dead time exceeds a first threshold, and a second switch that is controlled to raise the reference voltage if the dead time delay signal is below a second threshold.
