Hi Kevin:

Sorry that I don't have calculation tools in hand. I'll check with team to see if they have any tools.

There is some details guidance in datasheet which could help you to do the calculation and choose the device. If it's still enough for you, we could help you do some calculation. But we need more details information.

Hi Kevin:

After check with team, the calculation tools: power stage designer is recommended to use. It's available in TI.com:

I have check your parameter, but i couldn't find the datasheet of inductance and the capacitance. So may you share more details materials for me?

Besides, may you check the requirement of the ripples? It seems need large inductance to achieve this target, like 68uH for single inductor.

Hi Kevin:

I think the Power Stage Designer is enough to calculate the parameter. So I'll close this post.

You could email to me to review the schematic and other device after the calculation.
