Hi Kevin,

I will give this priority on Monday.

One thing that comes to my mind looking at the schematic is, please add a placeholder for the snubber resistor (1ohm, 0805, check power rating) and snubber capacitor (1nF, 0805).

Regards,

Gerold

Dear Gerold,

So the snubber place holder will be SW to ground, right?

Yes Kevin. The sunbber resistor/capacitor will be from SW node to PGND.

I will follow up with you by email on the schematic review comments.
