Abstract
A method of operating a DC-DC converter includes generating a high-side control signal for a high-side transistor and generating a low-side control signal for a low-side transistor to thereby cause conversion of an input voltage to an output voltage. A time shift is measured between a falling edge of the low-side control signal and a time at which a drain-to-source voltage of the low-side transistor becomes higher than a set threshold voltage. A time shift error is determined as a difference between a dead time and the measured time shift, with the dead time being a time between the falling edge of the low-side control signal and a rising edge of the high-side control signal. A frequency of the high-side control signal and the low-side control signal is adjusted, based upon the time shift error, to maintain the DC-DC converter as operating in critical conduction mode.
