UC3872: Production Life time for this chip

Hi Laurent

Please let me check and get back to you later.

Thanks and best regards.

Hi Laurent

I checked internally that we don't have refresh plan for this product. 

Can you please share your End equipment and application needs? What feature needed?

Thanks and best regards.

Hello,

 Thanks a lot for your research.

 It will be for a new product and we expect a product life until 2035 (minimum).

The quantity is 500 parts / year. It’s a big product with low quantity.

This product embeds a high voltage generator.

The UC3872 is very interesting for his push pull feature with zero detection to minimize loss.

The electronic schema is a push pull DC to AC converter from 24 Vdc to 6 KVrms (like the application notes schema in the datasheet, it’s work fine )

 I have another solution with more discrete components. The UC3872 will allow to integrate the solution.

 Have a nice day.
