TPS2H160-Q1: TPS2H160 spice model issue when used in LTspice tool

Ummaiah B

Part Number: TPS2H160-Q1
Other Parts Discussed in Thread: TINA-TI

I see convergence issues, simulation not completing, when TPS2H160 spice model is used and run in LTspice (Analog devices Electrical Simulation Tool) when these are in parallel or single with Resistive Inductive load, please see schematic below/attached.

Please suggest on how to fix it. Hoping this a simulation model related issue.

I have no issue while running with pure resistive load wither single or parallel, working a expected.

Hello,

While both PSPICE and LTSpice are SPICE sims, there are some significant syntax changes that would have to be made before a PSPICE model would work correctly in LTSpice.

I highly recommend using a PSPICE simulator if possible.

Another option is to use TINA-TI (this is a TI SPICE base simulator that is free to the public): https://www.ti.com/tool/TINA-TI

Just like with LTSpice some changes have to be made to convert a PSPICE model to a TINA-TI model. Please refer to this training video for information on how to do that: https://training.ti.com/importing-spice-models-tina-titm-simulator?cu=1127691

Best Regards,

Another option is ordering the Evaluation module which will provide you with the most accurate device behavior.
