  RE: TPS546D24A: Calculating the output impedance modeled as a series RL circuit (VRM model)

  Mehmet Ali Anil1 No, that was my typographical error, # of Devices should be on the bottom instead of the top. I will edit the original post to correct it. It should be (CSA / # of Devices) * VOUT_SCALE_LOOP / VLOOP. For a 4-phase design using...

  RE: TPS546D24A: A version

  Tommy Tzeng No, the TPS546D24 and the TPS546D24A are not exactly the same. They are pin to pin compatible, use the same power path components and the same control loop architecture. They also share most of the same PMBus commands along with using...
