LM2675: Simulation of DC-Converter with unencrypted model LM2675 in LtSpice.

Part Number: LM2675

Hello,

I tried to simulate a dc-converter with the unencrypted spice model LM2675 with LtSpice.

After about 7us the simulation is slowed down extremely. After 10 minutes I stopped simulation. 

It seems as if the switching does of the model does not start.

I simulated also without the .options and without startup in the "edit Simulation command". Same result.

What can I do?

with kind regards

Peter
