Hi Team,
My customer is asking how to calculate ripple current of an individual output cap. For example, they use 2*47uF ceramics and 2*470uF/2.5mOhm MLCC. The inductor current is 600kHz, 15A pk-pk. They want to know what is the RMS current in an individual MLCC so that they can know lifetime of that cap in advance.
Any ideas or consideration for this?
Thank you very much!
