Hi,

My customer has question about LMR14030SEVM.
Could you tell me about questoin?

[Question]
LMR14030SEVM has the small output capacitor C7.
It is far from inductor. What is the function of C7?

Best regards,
tateo

Hi Tateo,

This is only for ripple test. As you know, long cable probe will cause large ripple, so we add a small cap at the test point for lower Vout ripple. This cap can be removed on ctm's system board.
