I am using TS30042-M033QFNR step-down voltage regulator.
The datasheet states to connect all the PGND pads together and then use vias to go to the 'general' GND plane on the back of the PCB.
In my design however, the 'general' GND plane is on the same side as the TS30042, so my question is, can I connect the PGND pads directly to the plane or do I have to separate them, and use a cluster of via to connect to a GND plane on the back (which I need anyway for thermal management) and then use stitching vias to re-connected to the main GND plane?
My understanding is that the two grounds have different purposes and thus must be connected only at one single point and thats the reason for the vias.
I am currently using the second alternative:
Edit: As requested my schematic and datasheet.
Is this a good design or not?
Thanks
