hello
I have used power integrations design tool "PIExpert" to design a DC/DC converter. I entered the parameters of the DC/DC converter to the PIExpert and it gave me the BOM, Schematic etc...
but it gave me a warning, that I do not understand what it means. The software wrote:
"Drain voltage close to BVDSS at maximum OV threshold. "
and it suggested the following solution:
"Verify BVDSS during line surge, decrease VUVON_Max or reduce VOR"
I have 2 questions:
1- what does this mean? and what is the expected impact for this warning?
2- what is the corrective action that I need to do? if I understand well, then this problem can be solved by adding a varistor, and connecting it with a in series, to prevent this surge , is this solution valid?
