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. 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 the output voltages are well matched. When connecting converter outputs, it should be remembered that the switching will not be synchronous, hence some form of coupling should be employed. One possible solution is to use a diode feed, this is suitable mainly for 12V and 15V output types only where the diode voltage drop (typically 0.6V) will not significantly affect the circuit functionality (see figure 2). With 5V and 9V supplies the diode drop is generally too large to consider as a suitable means of connecting paralleled converters. This method also Copyright @ Shenzhen Sunyuan Technology Co., Ltd.
