I'm tring to simulate LTC3895 buck controller.
My specs: 80V input
Control Mosfet : BSC093N15S5 ( x4)
Sync Mosfet : BSC093N15S5 ( x2)
Output Cap :1mF-150mR Cap ( x4)
My question is when I put the 4.4uH inductor, It shows the Ploss for control mosfet is 0.529Watt but When I put the 4.5uH inductor, It shows the Ploss for control mosfet 1.221Watt. Note that; I just changed the inductor value.
Why is it happening ? are there any logical explanation ?
By the way, I know the ripple current for inductor is too much. I just want to ask the problem.
for 4.4uH results;
for 4.5uH results;
