Abstract: Disclosed is an N:1 (where N is an integer such as 3 or higher) resonant star topology converter to generate an input supply (e.g., 1.8V) for a processor (e.g., a system-on-chip (SOC)) from a higher power supply source (e.g., 12.6V) such as a battery or other source. The resonant star topology based regulator can be realized by a combination of on-die and on-package components as opposed to voltage regulators on motherboard with discrete inductor and capacitors. In one example, capacitors of the N:1 resonant star topology are implemented as multilayer ceramic capacitors (MLCC). The architecture of the N:1 resonant star topology based regulator results in high bandwidth. For example, compared to traditional step-down voltage regulators, the N:1 resonant star topology based regulator exhibits ten times higher bandwidth.
