Printed Circuit Board Layout Considerations
Use the following general guidelines when designing printed
circuit boards:
1. Trace out the high current paths and use short, wide traces to
make these connections.
2. Connect the PGND Pin of the ADP3416 as close as possible
to the source of the lower MOSFET.
3. The VCC bypass capacitor should be located as close as
possible to VCC and PGND Pins.
