LMZ14202H Output capacitor Problem

Other Parts Discussed in Thread: LMZ14202H

Dear all

Our customer has a trouble.
The output setting is 12V, but the output becomes about 2V.

The waveform is following;
Yellow:RON, Green:SS, Purple:FB, Blue:OUT

I checked customer's schematic.
I found that the output capacitors was ceramics of 16V.
This parts has only about 30% capacity on 12V condition.

In this case, does it become such a condition(waveform)?

Regards,
PAN-M
