Is there any SPICE average model for LM5146 controller?
I found unencrypted transient model on TI website but not average model of it!

Hi Amin,

You can also take a look at the LM5145 product folder to see if any model is available. I have a SIMPLIS model if that helps. I assume you nee dthe AVG model for loop analysis, but SIMPLIS is more accurate for this than PSPICE.

Regards,

Tim

Sure, here it is – please update as needed. The model is useful in particular for looking at load transient response and bode plot.
