note that the above working circuit inductors are individual, NOT common mode ones. PCB is 4-layer
and I built another 2-layer PCB, when the output capacitor(no matter 1uF or 2.2uF) connects after the inductor is connected, the IC will auto-reset most of the time without any reason.
I need help on this. below I attached the current circuit.
difference between 2 circuits:
1. working board 4-layer VS reset board 2-layer
2. output cap 2.2uf VS 1.1uf
and I could not find out more reason that it resets, need help
