Hi,
I am ADI DFAE of Anstek from Taiwan,
My customer has one application that is Vin=12V/ Vout=1.4V~1.6V (use program control output voltage) / Iout = 300A.
So we will use the LTM4650A + LTC2971 in this application.
We have two issue as following:
1. I don't find the application circuit data of 12-phase 300A in datasheet, Could you provide application circuit of 12-phase 300A for me ?
2. we use LTC2971 to Manage LTM4650A's output voltage, Is it suitable? If not, could you give us other suggestions??
If you have any issue, please let me know. Thanks!
Best Regards
Klex
Hi Klex
I will let the LTM4650 support person answer the first question.
Re: the LTC2971 managing the 4650, you won't need the high voltage capability to manage a 1.5V rail. This might better managed by the LTC2972. Have you considered using the LTC3888? It has PMBus functionality built-in. This could replace the 4650+2972. There are a few multi-phase examples in the datasheet.

Hi Mike,
Thanks very much for your reply.
Customer has LTM4650/LTC2971 in stock. they are worried about the delivery time issue, so they don't consider the LTC3888 for now, unless the LTM4650/LTC2971 is unattainable.
