hii.. i wnt to learn how to make a spice model language because i want build tps54260 and now i am using proteus design tool for this so help me guys..
There are programs that help you to do this but they are a bit expensive, and also require many measurements to get it right. I doubt you would want to go through all that.
It does help to know the part well, in which case sometimes you can sit down and write a spice file yourself that models what you really need and maybe not every single aspect of the device. A very simple example of this would be to model a transistor as a perfect switch with some series resistance, which would work in certain restricted analysis scenarios.
Do a search on "SpiceMod" and see what comes up. You'll have to check if this will work for your product too i guess. I havent used this program yet so i have limited info on it right now but you can read up on it.
You might be able to make one from the drawing their data sheet shows, this is often possible as long as they give enough data on the internal workings of the unit. You could probably model the major features if you have ever made a model of a converter before. If you havent it may be worthwhile for you to make a simpler spice model first and make sure it works.
Now that i see the data sheet im not sure if there is going to be a program that will make a model of that ic because it has a lot of features. You'd probably have to do each internal part yourself separately, using built in MOSFETs and op amps.
I did several models of ic's in the past but it does take time to get all the internal parts in there and working right and making sure it converges.
Would it be enough to work with a regular buck converter to start with and see what happens?
Since you use Orcad, you can go to the following link for the transient model TI has of the TPS54060... it's about 2/3rds down the page under "Simulation Models":
