BXXXXD/S-2W SERIES DC-DC CONVERTER CONNECTING DC-DC CONVERTERS IN SERIES
Galvanic isolation of the output allows multiple converters to be connected in series simply by connecting the positive output of one converter to the negative of another (see figure 1). In this way, non-standard voltage rails can be generated, however, the current output of the highest output voltage converter should not be exceeded. When converters are connected in series, additional filtering is strongly recommended as the converters switching circuits are not synchronized. As well as a summation o.
