TPS62873: input/output capacitor

Hi,

   I found in the application note there is a Cload which has hundreds of UF. So this should be the answer of my first question. However, a new question is what is the difference between Cload and Cout? 

Hello Zehui,

Thanks for reaching out to us.

The Cout is the output capacitors placed closed to the buck converter IC, which in this case is TPS62873. On the other hand, Cload pertains to the capacitors placed near the system load or SoC to achieve the ripple and transient load requirements.

I hope I was able to address your queries.

Best regards,

Excel

Hi Excel,

I understand this. Is Cout+Cload in the application note equal to Cout in the datasheet? Their values are similar.

Hello Zehui,

If you don't have further questions, can you kindly close the thread?

Thank you.

Best regards,
