Re: integrate components from Texas Instruments
You cannot use this model file with LTspice. It is encrypted and will only work with PSpice. Similarly, if you? encrypt a model with LTspice, that cannot be used with any other simulator. I didn't

Re: integrate components from Texas Instruments
I uploaded the library file under 'files'; I'm still not quite familiar with the forum here. The IC in question is the LMR51635XF. But in general, I have trouble properly integrating ICs, especially

Re: integrate components from Texas Instruments
It would be simpler if you just said which component you're trying to make a symbol for. You're getting errors? What errors? We usually don't advise tryi

Re: integrate components from Texas Instruments
I strongly advise against YouTube videos. Instead, follow the instructions in the LTspice Help 'Third-party models'. Do not add anything to LTspice native files, because that makes your copy unique

integrate components from Texas Instruments
Hi, I'm new to the group and also still a beginner with LTspice. I'm currently using LTspice 24.0.12 ¡ª should I rather download the newer version? My actual problem is that I want to integrate

Re: Sine modulated PWM voltage source (PWL file=xxx)
Thanks, Dennis, for pointing that out. At the moment I'm trying to get the points row defined by fixed time points with relative steps between each new pulse. It is allowed to change between absolute

Re: Diode TVS like zener in LTspice??
Andy, you're not quite right. Here is my clarification: .model SMBJ24CA D(Ron=.65 Roff=50Meg Vfwd=25 epsilon=6 Vrev=25 revepsilon=6 Vpk=24 mfg=Littlefuse type=TVS) .model SMCJ33A D(Ron=.4 Roff=8Meg

Re: Sine modulated PWM voltage source (PWL file=xxx)
Thanks, Andy. I¡®m after it. Probably my formula is producing this wrong input. And what my confusion about the file syntax is concerned, I¡®m on track again . I was totally besides the rails :)

Re: Sine modulated PWM voltage source (PWL file=xxx)
File format?? No.? The file formal for a PWL file is ordinary text. Data format?? Possibly. PWL data is always pairs of numbers, where the first number of the pair is time, and the second number is

No, not necessarily.? There is a checkbox when you upload, which sends an auto-generated message, which most everyone ignores, and it self-destructs in a few days.? We ask that you always *compose*
