Printed in P.R.C January 2007 Page 2 of 4 SHENZHEN SUNYUAN TECHNOLOGY CO., LTD. WRExxxxS-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 of the ripple voltages, the output could also produce relatively large beat frequencies. A capacitor across the output will help, as will a series inductor. www.DataSheet4U.com CONNECTING DC-DC CONVERTERS IN PARALLEL If the available power output from a single converter is inadequate for the application, then multiple converters can be paralleled to produce a higher output power. However, it is not recommended to parallel converters to generate a higher power output, please select our higher power output modules or contact us for a customized solution. It should be noted that it is always preferable to parallel multiple converters of the same type. For instance, if a 2.5W converter is required, then either 2pcs AxxxxS-2W should be used or 3 AxxxxS-1W, not an AxxxxS-2W and an AxxxxS-1W. The reason for this is that the output voltages are not sufficiently well matched to guarantee that an AxxxxS-2W would supply twice as much as an AxxxxS-1W and the situation would occur where there was only 1W being drawn from the AxxxxS-2W and 1.5W from AxxxxS-1W. Even with paralleled converters of the same type, loading will be uneven, however, there is only likely to be around a 10% difference in output load when.
