Input capacitance
The ceramic input capacitors should be placed as close as possible to the
VIN/PGND pins to minimize the connection impedance. For the same reason,
multiple vias are placed close to the capacitors' terminals, utilizing inner layers to
connect to input pins of the module.
Note there are places for additional input capacitors on the bottom side of the
board, see section 7.
Placement and connections of the larger bulk input capacitor (used mainly to hold
up the input voltage during large load transients or changes in input voltage)
follows the rules of the ceramic capacitors described above.
