WLC38 + STWBC86 - 5W Reference Designs?

[AnkhInnovationsLLC]

So it looks like there are 2.5W or 15W reference designs, does anyone have a 5W reference design?

Hi

2.5W reference designs,

5W reference design same with 15Wreference design

When WLC38 work in BPP mode, it is 5W.

Can't find 2.5W reference design. TN1440 . "SORRY, PAGE NOT FOUND". Can someone help please ?

Are TVSes and RCL resistor needed in this power level ?

I'm also looking for the STWLC38 and STWBC86 reference material - especially the 2.5W reference design, but it appears that ALL material (datasheets, product pages, etc.) has been removed. Could you please follow up with me also on this material? Thanks.

All links and all data sheets no longer work...

Like what goes on at ST that warrants changing the link to every single data sheet across every product?

Hi did you manage to find a schematic the link provided does not seem to work

Can you please let me know where I can find these reference design? All of the links I followed ended up as broken links. Specifically looking for reference layout for 2.5W and 5W of the STWBC86 IC.
