Abstract
A buck-boost converter having dual-folded bootstrap for driver metal oxide semiconductor (DrMOS) device that, in addition to the traditional bootstrap capacitors, include folded bootstrap capacitors that cross-couple inductor nodes to the two sets of DrMOS switches. The DrMOS switches can be n-type or p-type, and can be replaced with driver Gallium Nitride (DrGaN) devices.
