    Monolithically integrated GaN power stage for more sustainable 48 V DC-DC converters
    (2024) Basler, Michael; Mönch, Stefan; Reiner, Richard; Benkhelifa, Fouad; Quay, Rüdiger
    In this article, a fully monolithically integrated GaN power stage with a half-bridge, driver, level shifter, dead time and voltage mode control for 48 V DC-DC converters is proposed and analyzed. The design of the GaN IC is presented in detail, and measurements of the single function blocks and the DC–DC converter up to 48 V are shown. Finally, considerations are given on a life cycle assessment with regard to the GaN power integration. This GaN power IC or stage demonstrates a higher level of integration, resulting in a reduced bill of materials and therefore lower climate impact.
