AC Transfer Characteristic for LM2597 Transient Model

Vladimir,

The PSpice model in the product folder is a transient model and cannot be used for a Bode Plot analysis. I recommend that you use WEBENCH® Power Designer to see the crossover frequency and the phase margin of the device in the OpVal table. You can modify the design to your specific requirements and the Circuit Calculator will give you the crossover frequency and phase margin.

Good!

Thanks you very much!
