Missing application note AN1965

Several production-active STM products reference application note AN1965, e.g. referenced in STA540's datasheet ( https://www.st.com/en/audio-ics/sta540.html ).

 

This application note seems to be about heatsink considerations.

 

Application note AN1965 is not available from STM, nor anywhere else I searched.

Can someone provide this application note?

Welcome @fff, to the community!

Please find the application note AN1965 attached.
Please note that it dates from 2004 and has not been updated since then.

Hope it helps?

I doubt the laws of physics/thermodynamics have changed much since then ... ?

 

But, if current documents continue to reference it, it should be kept available!

A complex system that works is invariably found to have evolved from a simple system that worked.A complex system designed from scratch never works and cannot be patched up to make it work.

That was the reason to make it available here.
