Author: Claudio Spini.

Hello Sir/Madam,
Question 1: The schematic on page 12/38 shows a connection between D16K & R34. (Note: D16 anode is connected to L6699 pin 3, CF). That connection is marked "connection made by re-work". I seek an explanation as to why this connection was done.
Question 2: Several components on the schematic are marked "N.M.", eg: D16, C43. What does "N.M." mean?
Many thanks!
Edit 02-Dec-2020: Added image below, the relevant portion of the schematic.

Hi @FBaro.1 ,
please open a new topic in the Power Management section
As above mentioned I am not in charge of resonant controllers, but if you post in the right place some others Community members can help you.
Have a nice day.
