MAX1747 switching regulator simulation software or SPICE model availability

Hi
Does anyone know a program where I can simulate a circuit based on "MAX1747" switching regulator, neither Eagle,ISIS,LTSPICE or Altium have this part in their libraries, I downloaded MAXIM library for Altium but this part doesn't exist in it, does anyone have an idea what program can I use to simulate a circuit with this part??

If Maxim have not produced a spice model, then you are probably out of luck. It is normal to produce a behavioral model for such parts, since most are so complex that the processing time would be too long otherwise.
If you are just wanting to have a look at how your SMPS will work generally, I suggest that you look for a near equivalent part from Linear Tech, and use LTSpice. If the internals are different, you might find the phase margin will be as well, and may result in an unstable control loop. For that reason, try and find a part that uses a similar internal topology.

Hi,

Have you tried NGSpice? or other online electronic simulators? I tried using an online simulator, but sadly, they don't have that component either.

Having just looked up the part number myself, which I should have done before my earlier reply, it is unlikely that there will ever be a Spice model for this part is my guess, since it is designed for a specific application, for which plenty of application information is supplied in the data sheets.
Since it uses charge pumps, look up the Maxim web site, they have a number of charge pump parts, see if any of them have a spice model. If you just want to figure out how a charge pump works, there are plenty of schematics available, model it with switches and capacitors yourself,
cheers,
