TINA/Spice/LMP8480: Simple simulation not working

Part Number: LMP8480
Other Parts Discussed in Thread: TINA-TI,

Tool/software: TINA-TI or Spice Models

Hello,

I need a simple simulation of LMP8480.

I am somehow new to Tina TI interface (coming from LtSpice), however, I still can't figure out what's wrong.
I selected the LMP8480 model from library and build a simple schematic that should work.

It complains about NC pins, however, I tried DC and Transient and empty results.

What's wrong?lmp8480_test.TSC

Hi rmalcovich,

Please make sure you are using the latest version of TINA-TI(v9.3.150.328 SF-TI). You can verify using from below link:
http://www.ti.com/tool/TINA-TI

It is recommended to connect jumpers to floating(NC) pins in TINA-TI and connect Meters to view outputs.
As you are new to TINA-TI, I would recommend you to watch training videos of TINA( link available in signature).

I just use the lates version 9.3.150.328 SF-TI
Is not working. Probably the LMP8480 model is the problem.

Can you open the TSC file I attached and check for me?

Thanks,

I was able able to run the schematic you shared. Please add meters(voltmeter etc) at desired node to see the results.

It's not working.
Please do a transient analysis and post it here.

Thanks.

Please find snapshots below:

Imran,

Exactly the plots I want to see!

I expect to run the circuit for 100uS and see the output at certain level, corresponding to transfer function of LMP8480.

When I try to add traces in Transient there is a empty list.
How can I see the R2 voltage in transient plot?

Hello?

Anybody here?

Hi,

Please add a probe to the node you are interested in. You can do that by clicking the "Meters" tab and place a "voltage pin" on the node of interest.

Thanks,
JC

Still blocked with Tina.
I added probe, like I said, other regular circuits works, this, including LMP8480 not.

I can't explain why don't you post a plot of your results.

Perhaps I do something wrong.

Hello,

The simulation that you see seems to be zoomed into a certain region. Please zoom out by clicking on appropriate buttons on the menu. This is what I see...
