This reference design is a 4-kW continuous conduction mode (CCM) totem pole power factor correction (PFC) with a top-cooled gallium nitride (GaN) daughterboard and TMS320F280025C digital controller. Along with the integrated protection features of LMG352x and C2000, full protections are implemented. AC drop, surge, and Conducted Emission (CE) are fully validated, providing a cost-effective, high-efficiency, and robust totem-pole PFC design with C2000 and GaN.
