7.4.2.2 Connecting the DCP01B in Series
Multiple DCP01B isolated 1-W DC/DC converters can be connected in series to provide non-standard voltage rails. This configuration is possible by using the floating outputs provided by the galvanic isolation of the DCP01.
Connect the +VOUT from one DCP01B to the –VOUT of another (see Figure 7-6). If the SYNCIN pins are tied together, the self-synchronization feature of the DCP01B prevents beat frequencies on the voltage rails. The synchronization feature of the DCP01B allows easy series connection without external filtering, thus minimizing cost.
Figure 7-6 Multiple DCP01B Devices Connected in SeriesThe outputs of a dual-output DCP01B can also be connected in series to provide two times the magnitude of +VOUT, as shown in Figure 7-7. For example, connect a dual-output, 15-V, DCP012415DB device to provide a 30-V rail.
