  • TI Thinks Resolved

TINA/Spice/OPA454: OPA454 PSpice model convergence issues in LTSpice.

Part Number: OPA454

Tool/software: TINA-TI or Spice Models

The PSpice model takes a long time to converge to a DC operating point in LTSpice. Then, even though I do a savebias (operating point) & loadbias, a transient simulation takes a long time to start. Is there an LTSpice-friendly version of this model?

  • Lance,

    We are unable to support our models in LTSpice. Have you tried the same model in TINA-TI (www.ti.com/.../toolssoftware) I t is a free simulator from TI and if you are new to it there is a short video training series that you will find very helpful to ramp up on the tool: training.ti.com/tina-ti-video-training-series

    All TI Spice Models can be found here | All WEBENCH supported devices can be found here

    New to TINA-TI? Its a free spice simulator! Try out this short Video Training Series

    Thanks, I'll give it a try & get back to you. However, it's more work if I have to regenerate my circuits in another tool because of one model.
