LTC3888 + LTC7051 design equations and LT power cad model

Category: Hardware
Product Number: LTC3888

Hi,

I have an issue in finding the output and input capacitor requirement for the design. I am designing it for main channel1 0.7-0.9V@140A with 3 phase and main channel2 0.8V@20A with 1 phase .

So can you help me out with the calculations and with the equation. Also, is there LT power cad model for the same.

I came across the below power tree, why is VCCH-SDM powered using LDO( AN-910 specifies switcher itself) ? and why at +0.9V, which falls outside the recommend voltage setting for Devices with F-Tile only.

Can i power VCCH-SDM using LTC7051 itself?

Thanks in-advance,

Deva
