TPS40140: Layout of GND versus PGND.

Bob Hewitt

Part Number: TPS40140

I'd like to get an example of a layout in a single ground system with a multilayer board where I can mitigate switching noise from the PGND getting into the GND of the controller.

HI Bob,

Sorry, we don't have layout example of single ground system.
It will be good to leave some distance between TPS40140 and MOSFET to mitigate the switching noise from FET to controller.

Thanks
Qian
