Application Example #1

Figure 18 shows an application example of a single isolated output solution for the PD. Both front auxiliary (FAUX) and rear

auxiliary (RAUX) power options are given, although only one option may be needed in practice. Note that for the RAUX option,

D2 is only installed when the supply voltage of the auxiliary power source would cause the V

Application Example #2

Figure 19 shows an example of an isolated, dual-output solution for the PD. The 3.3V output is tightly regulated while the 5V

output is cross-regulated. Both front auxiliary (FAUX) and rear auxiliary (RAUX) power options are given, although only one option

may be needed in practice. Note that for the RAUX option, D2 is only installed when the supply voltage of the auxiliary power

source is lower than 14.5V.
