Why DDR termination regulator part number is changed?

Question

Hi,

I am designing a custom board based on picozed 7015/7030.

While looking at the revision history of picozed, I noticed that the DDR3 Termination regulator (U4) part number has been changed in revision D from TPS51206 to NCP51400.

I am curious to know the reason behind this decision. Is there any issue with TPS regulator? Can I use TPS51206 in my design?

regards.

Hi,

Feel free to use what you wish in your design. We we changed to the NCP51400 due to it being less expensive and it also being more line card friendly than the TpS51206. Both are adequate for the task.
