You didn't swap U4A and U4B in the schematic
I thought it would be not necessary if I rotate the op-amp. I will try it now hoping it won't require me to re-do everything.
Are you autorouting? It should not be done for such a simple design...
No, I never did it and don't intend to.
If you followed all my instructions, there should only be 4 vias in the linear section, 1 for each gate and 1 for each source.
one for mosfet gate and one for mosfet source x2 ?? I will swap U4A and B to see this.
There will be a few vias for GND as well, but no jumpers to the red side.
I increased GND vias so that they share the current, despite being so little in the op-amp area.
There would also be 1/2 vias by the 1000uf caps, but nowhere else.
I didn't understand this.
There are 100% complete straight paths everywhere else if you placed the SMD caps/resistors correctly.
What is wrong with some of the traces going a bit further or bend a little bit? I see it all the time in PCBs. Yes, straight and short is the best though.
Also, what is it with that oddly placed resistor I have the red arrow pointed to?
this one delivers the EN voltage to the switchers. and the pins of the switchers are very far in the next side and cannot be rotated as you can see. either put the resistor in linear side then do the big trace or the opposite.
I will try more now.
