Application Example #2

Figure 32 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.
