7.4.2.2 Connecting the DCP02 in Series

Multiple DCP02 isolated 2W 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 DCP02.

Connect the +VOUT from one DCP02 to the –VOUT of another (see Figure 7-7). If the SYNC pins are tied together, the self-synchronization feature of the DCP02 prevents beat frequencies on the voltage rails. The SYNC feature of the DCP02 allows easy series connection without external filtering, thus minimizing cost.

The outputs of a dual-output DCP02 can also be connected in series to provide two times the magnitude of VOUT, as shown in Figure 7-8. For example, connect a dual-output, 15-V, DCP022415D device to provide a 30-V rail.

All 5-V, 12-V, and 15-V input voltage designs require a 2.2-μF, low-ESR ceramic input capacitor, while 24-V input applications require only 0.47 μF of input capacitance.
