8.4.2.2 Connecting the DCV01 in Series

Multiple DCV01 devices 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 DCV01.

Connect the +VOUT from one DCV01 to the –VOUT of another (see Figure 8-7). If the SYNCIN pins are tied together, the self-synchronization feature of the DCV01 prevents beat frequencies on the voltage rails. The synchronization feature of the DCV01 allows easy series connection without external filtering, thus minimizing cost.

The outputs of a dual-output DCV01 can also be connected in series to provide two times the magnitude of +VOUT, as shown in Figure 8-8. For example, connect a dual-output, 15-V, DCP012415D device to provide a 30-V rail.
