This reference design is an inverting SEPIC (Cuk) Converter powering 50-W continuous and up to 70-W peak. The used Cuk topology provides continuous currents at input and output, which allows the lowest conducted emissions in both directions. Compared to an inverting flyback radiated emissions are low as well due to no RF ringing at the switch node.
