Tool/software:
We are using the LM5143A-Q1 to build a 4-phase synchronous buck converter. During testing with 30 V input voltage, 15 A input current, and 15 V output voltage, we applied a 5 A load using an electronic load. We observed that the output current has a ripple variation of about ±3 A.
Could you advise what might be the possible reasons for this behavior and how we can improve it?
Please find the schematic and quickstart design below.

Thank you for your support.
