Hi,
We wissh to use the 4.7uH inductor IHLP8787 with our surge buck converter, which only works for 500ms at a time. (ie during the surge , to protect the input from the surge)

Vin = 175vdc vout = 36vdc, iout = 8A, fsw = 350khz

IHLP8787 4.7uH inductor

The core loss calculator for it gives a nonsense output.

Is that because the voltage is too much?
 

What result are you actually getting from the calculator? I mean, you are calling the value unrealistic. Why?
