Hi Sir 

the TPS53647 (4 phase) and TPS53667 (6 phase) are P2P solution. May we know what different between these 2 device?

The customer request around 120A output, which one much suggest?

If TPS40425RHAR/TPS53667/TPS53647  all can use CSD95372BQ5M and CSD95490Q5MC power stage? 

I think it is ok, just impact efficiency. or something i have need notice? pls advise.

    Hi Bogey,

    The major difference between TPS54647 and TPS53667 is max phase numbers. TPS53647 is 4phase max and TPS53667 is 6 phase max.
    If customer requests around 120A max output current., I would recommend TPS53647.
    I am not sure about TPS40425, TPS53647/TPS53667 both can use CSD95372B and CSD95490 power stages. It may impact efficiency and cost.

    Thanks,

    Nancy
