HI Hasan,
You can check your circuit with the LM5117 quickstart calculator https://www.ti.com/tool/LM5117QUICK-CALC . Make sure it's stable in CV mode first before checking CC mode. See also this app note on CC/CV operation: www.ti.com/lit/snva829…
Tamazaki-san,
Yes, you can replace with ceramic. 3-5pcs of 47uF is typically sufficient. You can use the LM5117 quickstart calculator to derive compensation component values - http://www.ti.com/tool/LM5117QUICK-CALC
Just use the derated capacitance…
If you wish to modify the Phase and Gain you will need to adjust the loop compensation. Please refer to the Quick start calculator for this.

Hope this helps?

Hi Gagandeep,
This is most likely a stability issue. Please use the LM5117 quickstart calculator to derive compensation component values: http://www.ti.com/tool/LM5117QUICK-CALC
Note that you should use the derated value of output ceramic capacitance…
