Dear Team,
My customer is evaluating the TPS92641 application by modifying the TPS92641EVM.
They increase V_IADJ from 0V to 2V (for V_CS=0.2V, ILED=5A). When ILED exceeds around 1A, on time becomes random or oscillalting. After than, constant current control also misaligns.
Please review their application specifications and settings attached below.

Can you please support us understand what cause this issue?
