Pspice To Ltspice Converter Weight
Anyone know if there's an LTspice to PSpice Schematics converter? And vice versa? It seems it should be relatively easy to do.

Is there a way to covert specialised component in LTSpice to PSpice? I'm doing a project that requires to use LT's Buck- Boost component (LTC3442), and since I have the main circuit in Orcad Capture, its practically impossible to redraw the entire circuit into LTSpice. Any idea to export the component so. Is there a way to covert specialised component in LTSpice to PSpice?

DCAC Converter simulation using Simple Model by LTspice. Hi all, I'm trying to find a suitable power fet to control a pulsed output. I found this Pspice model and thought I worked out how to convert it to LT.
Any idea to export the component so that it can be use in Orcad, or converted into PSpice library? Best Answer: It is not possible. The LTSpice dc-dc converters are 'hardcoded ' into the system for max. Simulation efficiency. They are not standard Spice models. It would not help you to mix a simulation model with an Orcad design, anyway. Analog simulation is not useful to simulate complete board level circuits and should not be used that way.
At least I have never seen it being used that way successfully. Never mind what the shiny PSpice brochure says. They are mostly selling to the unexperienced. You need to break out the part of your circuit that is of importance to you or that has a problem. Then you simulate several model levels of it (e.g. A linearized feedback model, an opamp model, a transistor level model) to understand how the mathematically ideal circuit behaves and how that differs from a component level model.
Then you optimize your component values, try to estimate the performance you can expect, and compare the theoretically estimated surge currents, voltage peaks, power dissipation, noise, drift etc. To the simulation. There are any number of important simulation issues in analog circuits that one can not address with the original design and where simulators like Spice allow to resort to different levels of modeling.

They should show up in your lab notebook, though. That you find it 'impossible to redraw' the circuit is not LTSpices problem. You just have to give up the illusion that analog simulation starts at the level of schematic entry.
It starts way earlier and it usually does not end until you are shipping the product. I often make dozens of simulations during the R&D phase of a circuit and again that many while I am debugging. And very often I start with a new schematic from of almost the same circuit from scratch because I want to make sure that I (as in capital I) really understand what I am doing. In case of a dc-dc converter I usually simulate the plain circuit and then I insert the estimated board parasitics. You will not find those in an Orcad schematic. But you will them on your board and they will cause trouble!
Converting Pspice To Lt Spice
If you are new to dc-dc converters, I can only advise you to REALLY read the data sheet. And every application note you can find. And every book you can find.
Theory is important to make these things work. They do not work magically all by themselves or by copying someones schematics. And debugging a dc-dc converter with poor layout is nearly impossible. So you need to know beforehand what you are doing. A colleague in my company quit last year. He had been given an assignment to make a really simple dc-dc converter and he struggled with it for a year. I had tried several times to give him the right pointers, but they never caught on with him.

I don't think he ever managed to understand theoretically how the circuits worked and which criteria he had to apply to optimize them for his particular application. It just shows that a simple switcher is not so simple if you need more than mediocre regulation, noise and efficiency.
