“…However, this requires very fast comparator and driver. Therefore, adaptive dead time control that minimizes dead time using feedback control is an effective solution [52], [57]. Many adaptive dead time controls are proposed including low f sw reports, but it can be classified in to two types.…”

There are continuous and strong demands for the DC-DC converter to reduce the size of passive components and increase the system power density. Advances in CMOS processes and GaN FETs enabled the switching frequency of DC-DC converters to be beyond 10MHz. The advancements of 3-D integrated magnetics will further reduce the footprint. In this paper, the overview of beyond-10MHz DC-DC converters will be provided first, and our recent achievements are introduced focusing on 3Dintegration of Fe-based metal composite magnetic core inductor, and GaN FET control designs.
