Hey there everyone, I have been trying to get my hands on the spice models for a couple of ICs from TI to no avail. They are the BQ24610 battery charging and power management IC and the TPS26636

Hello Andy, I am sorry. Next time onwards I will not include links that are hidden behind a paywall. Although, I do have a downloaded version of the paper which I am not sure if I can upload here (can

Thank you for such a prompt response, Andy. The error that I got during many iterations was "MEASUREMNT FAIL'ed" while trying to set appropriate TRIG and TARG conditions. I had mentioned the command

FYI, that paper requires membership in IEEE to access it.? It would not be a good idea to refer to a research paper that many members can not see without paying for it.? If there is publicly

What is/are the .MEAS command(s) you used? What is the error message you saw? Please don't leave us in suspense.? It does not help to tell us that you get some unspecified error, from a .MEAS command

Hello everyone, For my thesis I am trying to analytically derive the small signal transfer function of a practical buck converter topology with all the parasitics included. I am using this paper as

Agreed!? That link to imgur.com was a Very Bad Idea.? Did you read the guidelines for this group?? Links to bad and dodgy third-party websites should not be used in this group. Andy

BTW, please don't include links to imgur or other dodgy external storage sites. If you have images etc. you want to share, please upload them to Photos </g/LTspice/photos>. For

Sorry, I missed that you were still looking for the CD4026. Unfortunately, the libraries don't include those parts. Somebody enquired about the CD4026 once before back in 2013 in the message thread

Thanks for the response Tony. I have looked through the most recent files, but wasn't as lucky as you to find CD4026/CD4033 included in the linked libraries. *[link to imgur.com removed by Moderator]*

You are right. 24.1.8 has not installed itself. -- This email has been checked for viruses by AVG antivirus software. www.avg.com

I guess you didn't search the Files </g/LTspice/files> section of the group's website. If you had searched for "CD4000 library" (in the top-right corner), you would have seen 18 hits.

I have randomly found this topic while searching for CD4026 library for LTS. Would you still be able to share your extended library? Thanks

That's not the 24.1.8 help, then. You must have looked at an older version.

thanks Andy. I am trying to learn LTspice and opa & this group for help at the same time of which may meet alot of new stuff. i ould try files/uploading later on.

Very possibly. I think that the new feature of .PARAM, to pass strings, needs to be clearly explained in the .PARAM Help, as, for example: /?.PARAM can be used in two ways: / /1. To pass a numerical

There is some chance that statement is still correct as it stands, though maybe confusing. Evaluating a parameter's value from its formula would apply only to parameters and formulas that can evaluate

Well, it's hardly hidden away. It's the third short paragraph in the .PARAM help: /To invoke parameter substitution and expression evaluation, enclose the expression in curly braces. The enclosed

It would not surprise me if they did not catch every instance in the Help that needed to be changed. You ought to point out where you saw that in the Help. Andy
