I have a customer that would like to follow the example on page 13 of this app note (Advanced Adapter ORing Solutions using the TPS23753) to have two power supplies OR'ed together (PoE and DC/DC).
- Is this the best approach?
- What signal from the DC/DC would they use to disable the POE PS? (Per this statement: Applications using option 3 with adapter priority may want to disable the PSE source)
- Can a PGOOD flag from the adapter DC/DC be used to disable PSE source once the adapter is plugged in?
Regards,
Ryan B.
