Hi,
I'm considering design a 12Vin to 1.2Vout/21A power supply by TPS549D22. It will supply 14pcs of DDR4 VDD, as the space is very limited. The part number of DDR4 is K4A4G165WE from Samsung and MT40A2G4 from Micron. The supply range for VDD should be 1.2V+-60mV. I'm worrying the voltage drop on PCB trace would beyond the 60mV limit. And, the remote sense of TPS549D22 can only compensate one of the 14pcs DDR4.
Do you have any advice for the schematic and layout? Or, is there a better solution than TPS549D22?
Thanks.
