TIDA-010042: One phase of interleaved buck converter is getting heated than other in tida-010042 MOSFET based design

Tool/software:

Hi,

In my tida-010042 MOSFET based design, one phase of interleaved is getting heated than other phase.I assume it may be due to current imbalance between two phases.When I am adjusting the duty of two phases(each phase is given separate duty), I have observed temperature is getting slightly balanced.What may be the real cause of this temperature difference.How can I solve this issue of temperature imbalance between two phases.If current imbalance is the reason, what is causing this issue?What are the design considerations that I should follow for properly balancing the current between two phases.

Regards,
