TINA/Spice/LMZ14202EXT: URGENT ISSUE: Pspice unencrypted model is not working in TINA.

Tool/software: TINA-TI or Spice Models

Dear all,

I am trying to simulate a power supply composed by the LMZ14202EXT. Using the unencrypted pspice model, the following error is returned when trying to run a transient analysis:

----> Operating point not found - Component: U2.D24

A similar issue has occurred with LTspice. Does any one have a working simulation for this device? 

Please mind that I don't have a license for Orcad, so I cannot use the Encrypted models.

Thank you in advance

Jose Pedro
