TPSM63610: Feedback control is unstable

Part Number: TPSM63610

Tool/software:

Hello,

I am an FAE at a distributor that handles TI products.
My customer created a constant current circuit using the TPSM63610, referring to the application note below.
My customer has currently created a circuit board and is evaluating it.
However, there are current fluctuations, and from what I can see of the current waveform, the feedback stability seems poor.
I would like to adjust the phase compensation, but the TPSM63610 does not have a COMP pin, so I cannot adjust it.
Could you please tell me how to adjust the phase compensation in this circuit?
