Hi,
Customer uses UCC28610 as flyback controller for servo drives. 15W
input voltage comes from DC bus after rectifier from grid. and customer use 3*680uF capacitance between bus(+) and bus(-). shown as picture is between "P" and "DCN".
When cut off the power supply from AC, and V(P-DCN)=60V, the IC stop work. but when V(P-DCN)=48V, UCC28610 restart.
Is there any solution for customer to avoid this?

thank you!
