Tool/software:

Hi,

previous DDR4 project used TPS51200. I would like to need a DDR5 part(like Micron MT60B1G16HD-56B:D) w/ VDDQ(max <1A) and VTT(max< 0.5A) on card.Do you have any recommend lower cost power parts?

Hi William,

For DDR5 we have a catalog of JEDEC compliant PMICs that would probably be overkill based on those current specs. Namely TPS53832A which is our lowest current version.

Does this device look useable for your application? Do you need to meet JEDEC requirements for your design?

Regards,

James

No need to meet JEDEC requirements for my design. Can we reuse TPS51200 for DDR5 VTT?I saw the spec that can support DDR to DDR4.

Hi William,

The TPS51200 only supports VTT so if your application needs VDDQ and VTT outputs, you would probably needs something like the TPS51916 or the TPS51116.

TPS51916 is the lower cost option out of those two.

James
