model for IR2110

[qirui]

Does anybody have the model for the IR2110?

I get one pragrammed in Pspice,but it does not work with Multisim 8.

I get one pragrammed in Pspice from https://ec.irf.com/v6/en/US/adirect/ir?cmd=catProductDetailFrame&productID=IR2110,but it does not work with Multisim 8.

Hi quiri,

Please be more specific about the problem. How does it not work?

1)Does is simply not deliver the result that you expect?
2)Do you get a convergence error?
3)Do you get some model specification error?

Thank you for your time, Maxish.

I think I've got some model specification errors,which are as followed:

In my opinion, there must be something different beteen Barkeley SPICE and PSPICE,that leads the errors.Unfortunately,I have not found it out.

Thank you for any response in advance!

[Maxish]

Your right. There many differences between the latest Berkeley SPICE (SPICE3F5) and PSpice. Multisim is actively trying to support Pspice syntax and models, but there may be shortcomings due to the lack of documentation. A case in point is the IR2110 model. It is very valuable for us run across such models as it allows us to improve our product. The problem at hand will be addressed for our next release.

For now, a potential fix may be to replace all instances of the keyword "TEMP" with the numerical value of temprature you want to simulate at - probably 27. That seems to get rid of the problem.

Cheers

Max

Thank you very much !

Hi, I'm also trying to simulate the IR2110 using multisim ver 8.  I'm using the pspice model downloaded from IR IC simulation page.

http://www.irf.com/product-info/models/sim/index.html

When I run the simulation the following error shows up:

Error: unknown subckt: on line 14:xu1 $13 $u1_open_nc2 $u1_open_nc3 $u1_open_nc $vcc $11 $12 $5 $vcc $0 $0 $6 $0 $7 ir2112__ir2112__2

Any ideas ???

Pat.

does anyone have a ready model for the ir2xxx driver that has been tested and working in multisim? can you please send me one if available.
