Hello,
I am trying to simulate the LM3488 IC using LTspice XVII tool. I downloaded the “LM3488 Unencrypted PSpice Transient Model (Rev. B)”.
For some reason, I am getting this error: “Fatal Error: u1:v_ifa: requires a minimum of 5 parameters. Only 3 specified.”
I did not find any guidelines of how to use the model with the correct parameters. From the previous discussion found on this forum, it doesn't seem to need any other parameters than the SS.
Any ideas what the problem might be?
Here is the SPICE error log:
