  • TPS2372: PoE input filter for NoN-Isolated design

    Resolved
    Part Number: TPS2372 Other Parts Discussed in Thread: TIDA-01463 Dear *, we selected TPS2372 for PD and on the PoE voltage we have two DCDC connected. 1) Should we only have one input filter like in TIDA-01463 ? 2) How is the input filter calculated…

  • TPS2372: Any filters are required to add between PD and DCDC?

    Resolved
    Part Number: TPS2372 Other Parts Discussed in Thread: TIDA-01463 , LM5165 , Hi, team In general, any filters are required to add between PD output and DCDC? I guess it depends on the system requirements, but I would like to understand when filters are required…

  • RE: TPS23754: CC2500 + AT1284P + TPS23754

    Hi Venu, Majority of our EVMs and TI designs focus on the power; if trying to design a data+power PD system, I recommend looking at TIDA-01463. This is PoE lighting application; however, at a high level, it is a good reference to see how we approached…

  • RE: TPS2372: [TPS2372]TPH, TPL,Bt pin

    Resolved
    Hi Keisuke, If the DCDC is non-isolated, then there would be no need for an opto for TPH TPL or BT. Instead it can be connected directly to a GPIO on the microcontroller. I recommend looking at what we did in TIDA-01463 as a reference. This is a non-isolated…

  • RE: TPS2372: TPS2372 LED driver advice

    Resolved
    Hi Howard, We also have our bulk cap as 100uF for our PoE Lighting design, TIDA-01463. Using a larger bulk cap is not unusual for a buck topology. There may be a spike of current when you connect the LEDs which can hit the operational current limit…

  • RE: MSP432P401R: Selection help on MSP432 or ...

    Resolved
    As you have mentioned there are two families of parts, the 'E' and the 'P'. The 'P' has the higher performance ADC while the 'E' has the integrated MAC & PHY. With regards to the POE, there are a couple of reference designs, one with the 'E' device…
