Abstract
In a dead time adjusting circuit, a switch voltage appearing at a connection node between a first output switch and a second output switch, which are connected in series between two different potentials, is monitored to detect a first dead time, which is from a time at which the second output switch is turned off to a time at which the first output switch is turned on, and a second dead time, which is from a time at which the first output switch is turned off to a time at which the second output switch is turned on, each of the first and second dead times being feedback-controlled to be identical to a predetermined target value.
