[TINA-TI or LTspice] Trouble with LM5002 simulation
« on: January 23, 2024, 10:49:18 am »
Hello,

I wanted to recreate the LM5002 circuit in the TINA-TI program which seemed to me to fit the Texas chip like a glove.



Unfortunately, the effects of this program quickly took their toll on me, and the circuit simply does not work properly, when it comes to output voltage.

In fact, I could say that the output voltage is close to the set input voltage instead of being increased. A factor that may be crucial in this case is that I had to import the LM5002 chip into the TINA-TI program, which I did using the Tools-New Macro Wizard function.

I downloaded this model of LM5002 from this manufacturer's link:

Is it possible that I am making some mistake in running the circuit here?

Alternatively, do any of you have an LM5002 model that can run on LTSpice?

I tried to use the same one (in .lib format) from the TI website, but it does not work the same as in TINA TI. When I prepared an alternative circuit with LT1371 in a similar configuration as boost converter, it worked (although it is, of course, an Analog IC, saved with the .sub extension).
