Abstract

A dead time detector detects when a dead time occurs in a switching regulator comprising a high-side switch and a low-side switch and generates an output signal based on a duration of the dead time. A first circuit generates a first turn-on signal to turn on the high-side switch and a first turn-off signal to turn off the low-side switch based on the output signal in response to a first edge of a pulse width modulated pulse. A second circuit generates a second turn-on signal to turn on the low-side switch and a second turn-off signal to turn off the high-side switch based on the output signal in response to a second edge of the pulse width modulated pulse. A controller generates drive signals to drive the high-side and low-side switches based on the first and second turn-on and turn-off signals.
