Component simulation

Hi,
I hope you're doing well,
I want to do the simulation of the auto switching power TPS2112A
is there anyone can help me,
how to do the simulation, and is there a simple and specially designed software for the simulation of electronic components



?

This is the classic one.

i cant find a librery for simulaion of TPS2112A

If you want to simulate that circuit with something like LTSpice (highly recommended, and free) you need a good model of the circuit.

If you can't find a model, your only option is to write one. There are plenty of books and other documentation on writing Spice models.

That chip TPS2112A doesn't seem to do very much anyway. It simply selects a voltage source at either IN1 or IN2 and delivers it at OUT. It is like a "power" analog switch. You could probably create a rough approximation of it with a few discrete components. That is, depending on exactly what the purpose is of the simulation and how accurate it has to be.

Or one relay.
