9.1.3 Connecting the DCH01 in Series

It is possible to connect the outputs of multiple DCH01s in series to provide non-standard voltage rails. The

outputs of dual output DCH01 versions can also be connected in series to provide 2 × the magnitude of VO (as

shown in Figure 25). For example, a dual 5-V DCH01 could be connected to provide a 10-V rail.
