Place the DCDC output capacitors as close as possible to their respective DCDC output pins (less
than 5mm away): DCDC_VDDIO, DCDC_VDDA, DCDC_VDDD.
Place the ground connections of the DCDC_BATT input capacitors as close as possible to both the
DCDC_GND pin and the ground connections of the DCDC output capacitors.
Place the ground connections of the DCDC output capacitors as close as possible to both the
DCDC_GND pin and the ground connections of the DCDC_BATT pin input capacitors.
Route the positive battery terminal on the power plane layer using a minimum trace width of 30
mils (0.762mm). A thicker trace may be required for longer battery trace runs (using a plane is
best).
Connect the negative battery terminal directly to the ground plane(s) as well as to the top and
bottom ground fill using multiple vias (3 or more).
