Abstract

Modern processor loads place stringent power delivery demands on power density, efficiency, and dynamic performance. Previous work presented a current sourced hybrid switched capacitor with all magnetics located at the input. This design is well-suited to a system-in-package (SiP) implementation, where high-quality input magnetics can be connected externally. This paper develops a control model for the current-sourced converter, with an emphasis on characterizing the converter's ability to respond to a dynamic load. The reduced order model shows converter operation maintains the benefits of a current type buck converter, but the switched-capacitor sizing has a significant impact on the control bandwidth. Sizing equations for the converter are derived and shown to match well with simulated results.
