LM73606QRNPRQ1 design simulation in PSpice not working

LM73606QRNPRQ1

I have been trying to simulate this device using PSPICE on both altium and Tina-TI, however, after connecting all the ports required (based on the webench designer and my own calculations), there's an error that I am not sure what's causing it. Here's a screenshot of the same:

I am also attaching the library I am trying to use for the simulation:/cfs-file/__key/communityserver-discussions-components-files/234/LM73606_5F00_TRANS.LIB

Hi Jenil,

Please run the PSpice files on PSpice: https://www.ti.com/tool/PSPICE-FOR-TI

I have been trying to download it, but it e keeps on asking me to fill personal details, and even after doing it, it doesn’t download but instead starts asking me to fill the details again…

I tried running this on PSPICE by orcad too and it still doesn’t work

Hi Jenil,

Please do the following:
Log out of TI web site.
Log into https://www.ti.com directly (not the PSpice registration page).
Go to Account->Personal information and fill in the missing information.
Logout.
Go to www.ti.com/.../PSPICE-FOR-TI and click download.
Follow the instructions on screen.

Regards,

Rahil

Yeah, that works, I am downloading it. I am just curious as to why it wouldn't work on PSpice I have. I have attached a screenshot of the same, i don't get the right voltage out (it's 0 apparently):

Hi Jenil,

Glad to hear it's working for you now. We recommend simulating all our models in PSpice for TI.

It is working, I wanted to ask if there’s a quicker way of simulating the transient model or getting a steady state response? With the step function of 20ns for 1.4ms it’s simulating way too slow. Thanks for the help

Hi Jenil,

Transient model in PSpice is unfortunately slow, the only way around it is reducing the number of points (lower accuracy)
