Hello,
I'm designing an IoT board which requires a wire range power supply 6 - 40V.
I chose the TPS54340 but I'm a little concerned about pcb layout.
My board has 4 layer and I use one of the inner layer to distribute the output power of 5V accross the board.
My main problem is I'm not sure about the way the vias should be placed in the output line.
In the picture no2 is shown my draft layout I made recently. I placed the vias in the whole plane of output line of 5V. Like picture no1 A shows.
But I feel like it's not the right way and it would be better to follow the plan B of picture no1. and place the vias only after the output capacitors.
I'm looking forward for your advice here.
Thanks a lot.
