We are using a pair of LM5122s in a 2 phase master-slave configuration. Although our design is higher power with external 12V power supplies for gate drive, push-pull gate drive boosters, your LM5122EVM-2PH exhibits the same symptoms, although not as severe. The problem is switching waveform jitter on the slave side only. On our design, we found that a 470pF cap on the sync line between the master and slave chips helped some, it caused the duty cycle of the sync waveform to deviate from 50% duty cycle. Our design has a significant current imbalance between the 2 phases of about 35%. Your EVM exhibits only a 5% - 10% current imbalance. Any help would be appreciated because our customer is screaming at us for a fix! Thank you in advance for your help!
