("AI Detector for ChatGPT, GPT4, Gemini") identifies the (first two) texts as
100% AI-generated (then I got bored). However, I don't think we need scribbr to tell us they're worthless :--)

LinkedIn thinks it has found a way for the AI copyright infringement barrier when attempting to scavenge
deep insights on specialized subjects. They might even have optimized out the 'prompt engineer.'

I will update the model, noting your revision, and upload in a day or two.

That might be a mistake that an AI would make, after finding so many other things on the 'net where it is misspelled that way.

The choice in the group's name would have been one person's mistake.? It may have carried over to all the articles too.? Heck, it's even possible that the AI wrote the article spelling it "LTspice", which the group's owner then edited to introduce that error.? It's possible that all individuals involved in that article never actually used LTspice.

It is definitely written by a human being, because it consistently misspells 'LTspice" (even in the name of the group).

cander shelter showed a link to an article at ""

There is considerable misinformation in that article.

It is not clear if the human(s) behind it know what they are talking about.? But I don't think it was written by a real living, breathing person.

The lack of any meaningful useful information suggests that it was written not to inform and educate, but to be clickbait.? It also says that it was written by an AI bot.? And we know what that means.

Carlos,
VISHAY makes a number of Photovoltaic MOSFET Drivers.
VOMDA1271, VO1263xx & LH1262xx.
They also have spice models available.
Some model files even include the .asy file,
All you need is to take the time and effort to search their web site.
Mike

I don't know if this helps, but are you aware that LTspice comes equipped with a 4n25 model?

Frank,

Thanks, I suspected there was something going wrong in that UCC5304 model, but had not gotten to that point yet.? Thanks for finding this problem with it.

If I remember correctly, this was not a published model, it was converted from another program to SPICE.

Hello Andy,
you are right about errors in the posted simulation circuit, e.g. duplicated vdd net label. The issue has been also dicussed at Edaboard

There's however a serious problem with the published ucc5304 model. Obviously the LTspice? has never been tested with common mode voltage between input and output.? Reason is inappropriate usage of global ground node "0" in the subcircuit. I made a little testbench showing the problem and post it along with corrected ucc5304 model.

?

Do you realize that by putting a single polarity voltage pulse across the inductor the power delivered from that source is ~0.8Watts?
This will heat up the IC and diode. Also, the common-mode voltage on the input is specified as -0.2V max. and the 1N4007 will let it
go way beyond that.

BTW, the circuit works fine as is, including UIC, when the alternate solver is used.

Several points:

1. ?The .ASY and .MOD need to be in the same folder as the .ASC, not a separate one.
2. It works if you delete UIC. Don't use UIC unless it's essential.
3. You set Trise and Tfall to 0, which is impossible. LTspice uses default values, which may not be suitable. I set them to 0.1?, but they could be bigger if you adjust Ton and Tperiod to allow for them.
   

I'm only using LTSpice at hobby level. I've created a component for bi-di current-sense amplifier INA181 from PSpice model supplied by TI and a little test schematic (/g/LTspice/files/Temp/ina181a1-test.zip). But using an inductor as load simulation stops with "Singular matrix" error. And with a resistor it gets very slow after a while and output looks not as expected. Maybe someone can make this work better.
