Other Parts Discussed in Thread: TPS65400

Hi,

My customer has question about TPS65400.
Could you tell us about question?

[Question]
My customer want to know the recommended Ca, Cd and Cg value.
In datasheet, there is only typical value.
How much is the recommended minimum and maximum value of Ca, Cd and Cg?
My customer want to use 10uF for all capacitor.

Best Regards,

Why not just use the recommended typical values? That is what was used in the reference design of the EVM. I'm sure they did not evaluate other values. They are just standard sizes, so there should not be any reason to use other values.

Hi Tateo,

As John recommanded, why not use the typical value? The Bom cost is lower. However, if customer insists to use 10uF, it should be no problem for bigger capacitance.
thanks!
Eric

Thank you for your support. My customer want to reduce the cost.
If my customer will use 10uF for all capacitor, they can reduce the kind of resistor. And they can reduce the cost.
