Hi,
I am using PMP4259 design and made pcb as per gerber file.
During testing when we load upto 300W no issue, at 400W load, out of 4mosfets(Rating - 600V, 30A) - 2mosfets get failed in both the arms.
Kindy suggest suitable solution to avoid the failures, all the values are used as per reference design of PMP4256
Thanks & Regards,
