26.4 A 12-to-1V 90.5%-Peak-Efficiency 721A/cm 3 -Current-Density Quad-Output Converter with One Shared DC Capacitor
Abstract
This paper presents a 12-to-1V 4-output hybrid DC-DC converter that shares a single DC capacitor among all outputs. This shared capacitor stores and redistributes energy, ensuring independent regulation at each output. The proposed design achieves a 721A/cm3current density and 90.5% peak efficiency at 12-to-1.1V at 2MHz, delivering up to 16A of total load current. The measured results during load transients shows there is no cross-regulation issue.
