Hello Tommy,

In the TPS54678 datasheet, if you follow the 8.2.2 topic you will be able to calculate step by step the different parameters of your design and adapt the Loop Compensation values.

If you follow Step one through Step nine, you should be fine.

Let me know if you have any questions or need any help with the calculations.

Thanks a lot!

Regards,
Dorian

Hello Tommy,

Unfortunately, we don't have an Excel tool calculator for this device.

I have other recommendations for performant, small and easy to use devices which will release soon. This device does not need the external compensation components.

I just sent you a friendship request. We can discuss the details in private message.

Let me know!

Thank you,

Dorian
