We are using TPS2373 in one of our application , We can power device from DC as well as PoE both . Whenever we are switching between PoE to DC everything is fine and switching is flawless . While when we are switching between DC to PoE. PoE power is going low then it again do renegotiation with PSE and then power is coming .
Please let me know following
1) Does this behavior is normal ?
2) How i can make sure that switching between DC and PoE happens without any voltage sag.
