Hi,

Is below PCB layout ok?

SW1 is in Bottom and SW2 is Top.

Thanks.

    Hi David,

    The vias going to add some inductance and cause some ringing in the switching waveform, leading higher emissions and/or lower efficiency. Although it might not be a major concern, it is recommended to run both the SW1 and SW2 nodes on the top layer with shortest possible trace between SN6507 and the transformer.

    Let me know if you have any further questions, thanks.
