Abstract

The energy demand of future computing introduces new challenges in voltage regulator design. This paper explores an inductor-linked single-input multi-output hybrid switched-capacitor power architecture with modular output cells for 48-V to point-of-load (PoL) chiplet power delivery. The unique inductor-linked configuration of switched-capacitor circuits enables high performance with a high voltage conversion ratio while achieving high efficiency and high power density. The architecture can be used, for example, to support multiple loads in a chiplet with many voltage rails from a high voltage input.
