Abstract
A control device for a switching voltage regulator having a high-side switch and a low-side switch to supply a switching voltage to a load includes a comparator configured to compare the switching voltage with a reference voltage to provide an enable signal to the low-side switch, and a spike detection circuit configured to receive the switching voltage and output an offset control signal to execute a time shift to the enable signal.
