Hi Jimmy,

We don't have such data at hand. May I know tps61500 is used for what application?

Is there a calculation formula for this capacitance?

Hi Frank,

Thanks for your support!

Our customer have another question as below:

1. Do AGND and PGND have to be separated?

2. Is there a calculation formula for this capacitance as below?

End equipment is IP cam.

Many Thanks,

Jimmy

Hi Jimmy,

1) it's recommended that connecting AGND and PGND with single point.

2) sorry we don't have such formula.
