Design Challenges of Fully Integrated DC–DC Converters for Modern Power Delivery Architectures

This letter presents recent design challenges of modern power delivery architectures and circuit techniques for them. Recent computational loads impose significant power output demands on dc-dc converters while ever-shrinking Internet of Things (IoT) systems demand dc-dc converters with small footprints. Consequently, fully integrated dc-dc converters are highly desirable in contemporary power delivery architectures thanks to their compact footprint, high power density, and fast output regulation. However, numerous challenges exist in fully integrating dc-dc converters, necessitating the investigation of various circuit topologies and complex regulation schemes to ensure proper operation and versatility.
