Hi,
We have designed Isolated Class 6 POE power supply as per reference schematics PMP22494_RevA_SH2.SchDoc using TPS23730 IC.
We have omitted J11 input through Adapter as in the reference design in our circuit, as the input would be through PSE switch or through POE injector.
Input is through Ethernet RJ45 only (Through PSE Ethernet switch or through POE injector). .
The POE injector voltage is 48V.
In the design APD pin is connected to PGND and PPD pin is left open
Classification resistors CLSA = 31.7 ohms (27 ohms + 4.7ohms) & CLSB = 130 ohms (120ohms + 10 Ohms)
The circuit would operate as usual with PSE input by performing class identification.
The problem is with the POE injector.
Would it work with POE injector.
Do I need to make changes in the ckt with APD or PPD pins?
