How to change efficiency of BUCK_CONVERTER?

[chevymanar]

I am trying to simulate a buck converter with a worst case efficiency of 80%.  I am using the built-in BUCK_CONVERTER that is in the Misc family.  It is working great, but its efficiency is 100%.

Can someone help me out?  Is it possible to change the efficiency of this part?

I should have mentioned that I am using NI Multisim 13.0 (Power Pro Edition).

Hello chevymanar

Basically it is not possible to change internally something that can variate the efficiency of this component however I was thinking that you can try to change the L, R and FS in the value tab.

That is the cost of simulate components something those work better than components in the reality.
