Driver dead-time control is a popular scheme in a synchronous buck voltage regulator to prevent the shoot-through issue. In addition to its impact on efficiency, dead-time control also impacts loop gain and system stability, especially under the critical load condition. In this paper, the influence of driver dead time on the synchronous buck converter is investigated, and some practical issues are analyzed and verified by experimental results.
