What pwm power management chips are there in ltspice?

Go to the ADI official website and search for it. The power source management chip, including the previous one from Lingte, should be able to be simulated on ltspice.

There are so many models, what problem do you ultimately expect to solve?

Is it better to break down the problem?

1. For example, what is the PWM controller used for? Buck boost or something else?

2. Should buck be synchronous or asynchronous?

Some chips are not simulated

I need a pwm controller to implement a flyback power supply, but I don't know which one is better.

Is that chip? See if there is any other alternative library

What if I don't have this spice model?

It's called Lt14xx, I don't remember the specific name
