TPS62933: Datasheet Equation 21

Cameron Perl

Part Number: TPS62933

Hey team,

I was trying to recreate the math done in the example of equation 21 and found the result to be 35.7uF rather than the listed 25uF. Am I doing something wrong??

Thanks,

Cam

Hi Zixu,

We were trying to reproduce the datasheet example with the values that were used in calculating the example result.

I guess what I'm trying to say is I think that either there is a math mistake in the datasheet example OR both my customer and I are missing something critical in the calculation.

Thanks,

Cam

Thanks for pointing that out, it seems that there is something wrong in the datasheet, will correct that.

Hi Ruby,

So just confirming - the result SHOULD be 35.7uF, right?

Thanks,
