Hi GARETH,

Is 85V~102.3V output voltage? If so, may I understand what is the input voltage?

Best Regards,

Steven

Hi Patrick

Thanks for your suggestion Is the output voltage of TPS92390 only 48v?

Hi Gareth,

48V is the max recommended voltage on OUTx pins, but TPS92390 uses external power FET, so it is ok to use this device in over 48V applications. But to protect the OUTx pins, it is also recommended to add ~10Mohm resistor between each OUTx pin to GND.
