Abstract:
An integrated circuit includes a detector configured to monitor a high-drive signal and a low-drive signal that drives a high-side switch and a low-side switch respectively of an integrated circuit switching regulator. The detector monitors both the rising edge and the trailing edge of each of the high-drive and the low-drive signals respectively to determine a timing overlap between the signals and generates a detection signal indicating a dead-time value proportional to the presence or absence of the timing overlap between the signals. An output circuit can be configured to process the detection signal from the detector to enable a correction of the timing overlap between the signals if timing overlap is detected.
