Are you sure the rights are philips property and not hypex property since they hired the inventor?
The quote comes from the Philips app note, dated March 2006, titled "LV MOSFET applications". Philips/NXP hold the rights to the patent, even though it is in Bruno's name. I checked this with NXP over two years ago, specifically because I needed to check the requirements for commercial use of the patent.

Thanks. I know I did not invent this license agreement myself, but I could not find it back. You're right, it was in that application note. I just didn't save a copy.

That app-note seems to have disappeared from the NXP web site now. I still have an electronic copy if anyone wants to see exactly what it said.

Hello, I'm new on this forum.
I projected PCB for an amplifier, and skipped Q3 and Q4.
Will this layout and PCB work?
Sorry, I'm amateur of PCB projecting and some routes are wired.

Btw. I'm not good at English.

Values of components are the same as on the orginal schematic (except transistors) but his names are diffrent.
Is it a good idea to use 2N5401 for driving mos-fet? (driver -Q6, Q9 on my schematic)

I cant buy orginal parts and I'd use other parts, or make amp on IRS2092, but i don't know which will be better and cheaper.

For Q6 and Q9 better choices would be BC369 or BC807.

2N5401 is fine for Q8 and Q10.

Or a better low VCEsat (biss) transistor such as PBSS5140T or 5240T or similar transistors would be an option.
