TIDA-010054: TMDSDOCK28379D

Hello,

You can find this question partially answered in the following two thread:

The short answer is that, the output capacitor selection depends on various factor, like expected maximum allowed voltage error, Load transients and used leakage inductance.

The equations in the design guide and in the posts I shared can be used as a starting point, but need to be verified by testing, as we did for the selected value in our design.

Best regards,

Andreas
