TPS62825: I cannot find the max value for Cout

Hello Alex,

Thank you for using E2E,

For TPS62825 I would recommend to follow the datasheet recommendation.

 If the customer want to further increase the output capacitor value, he should reduce the inductor value in the same factor, but please make sure that you would expect higher ripple current with small inductor which would effect the efficiency of the device.

But if you would like to place larger capacitor far away form the device, then it should be okay, there is no need to change the inductor, just use the recommended inductor and capacitor near to the device.

Thank you,

Regards,

Moheddin.

Hi Moheddin,

Just one more question.
Do we have any simulation tool for our bucks where the customer could change the number of capacitors or enter a combination of capacitors?

Best regards,
Alex

Hello Alex,

We have SIMPLIS and Pspice transient models in ti.com

Please have a look - TPS62825 data sheet, product information and support | TI.com

Hi Moheddin,

Thank you for your feedback!

Do we have any tool simulation similar to webench where it is possible to change the number of output capacitors?

Best regards,
