Abstract
A driver circuit includes monitoring circuitry (32, 34, 36) for monitoring the states of high and low side switches (6, 8). The driver circuit has an adjustable delay for turning on the transistors (6, 8). The delay is decreased when the monitoring circuit detects that a voltage corresponding to one transistor passes a predetermined voltage V1 before a voltage corresponding to the other transistor passes another predetermined point V2, and vice versa.
