T2080 Regulator Query: LTC3877

[KLN]

Hi Team,

We are using T2080 in one of our design.

Our total T2080 processor current calculation came around 24A. We are planning to use LTC3877 

VID Control regulator which is capable of 60A when Dual channel combined. 

Since our current is maximum of 24~25A, Can we use single channel of LTC3877 to make use of 30A of LTC3877.

In previous designs with T4241, Processor current of 56A, LTC3877 Dual Channel combined Output (60A Capable Dual channel combined) was used.

Please confirm, In our case Single channel of LTC3877 can be used?

Thanks.

Hello KLN

Hope this post finds you well,

Yes, it can be used as long as you supply the necessary current consumption.

Hi @Hector_Villarruel 

Thanks for your reply. It's not clear.

What do you suggest us using Single channel LTC3877 (30A) or Dual Channel?

As previously said, Current consumption of core(max) is 24~25A.

Can we go ahead with single channel?30A?

Hello KLN,

Regarding to your question:

Can we go ahead with single channel?30A?

Yes, you can go ahead as long as you supply the necessary current consumption using a single channel.

BR,
