TPS2378: Isolated TI solutions

John Lin41
Intellectual 260 points
Part Number: TPS2378

We are planning a 802.3bt dongle network card and USB3.1 charger.

 

I/O: bt UPOE RJ-45 (1000Base-T or MultiGig PHY)

I/O: USB3.1 type C interface (PD source when UPOE plugged or PD sink w/o POE plugged)

 

Could you please recommend the following in TI solutions?

  1. isolated power solution/reference design, 48-60Vin(UPOE) => 20/9/5Vout/3.5A

  2. UPOE PD interface

  3. USB3.1 PD source controller

THANKS~

    Hi John,


    I have noticed that some time has passed and am wonder how you are doing? Are you still looking for recommendations for your design? I have removed my previous reply & restated my clarifying questions, below:
    - Would you be open to considering an IEEE 802.3bt compliant design?
    - How much power do you need for each output? Can the 9V & 5V be POL outputs derived from the 20V isolated output?

    Thank you,
