Hi,

Is a 3D model for the UCC33420 available? I have already checked the TI website.

Thanks and best regards,

HI Patrick,

Here is a 3d model in the .obj format.

I hope this answers your question.

Hi JCHK,

Better but I actually thought more something that looks like this (picture from UCC33420 datasheet):

E.g. more detailed

Hi JCHK,

Exactly what is needed. Is it possible to send/export as .step instead of .obj?

Hi Patrick,

I used an online converter and the result is a very large file. Not sure if this works.

Hi JCHK,

Thanks. What I have seen just now is that the leadframe is not correct. When I look into the datasheet the pins 3, 4, and 5 are connected and pins 9, 10 and 11 are connected. That does not match with the leadframe in the 3D model. By the way I know now how to handle the .obj file.

Regards,
Patrick

Hi Patrick,

I made the corrections. Here is the updated .obj file.

Hi JCHK,

To me it still looks not correct. If I look to the bottom it seems that the sides are flipped. Also the leadframe does not have the same shape as in the second .obj file. Also scale seems to be wrong (factor 10 smaller).

Patrick
