ADP3418
PC BOARD LAYOUT CONSIDERATIONS
Use the following general guidelines when designing printed
circuit boards.
Trace out the high current paths and use short, wide
(>20 mil) traces to make these connections.
Connect the PGND pin of the ADP3418 as closely as
possible to the source of the lower MOSFET.
The V
CC
bypass capacitor should be located as close as
possible to the VCC and PGND pins.
Use vias to other layers when possible to maximize thermal
conduction away from the IC.
The circuit in Figure 15 shows how four drivers can be
combined with the ADP3188 to form a total power conversion
solution for generating V
CC(CORE)
for an Intel CPU that is VRD
10.x compliant.
Rev. B | Page 12 of 16
Figure 14 shows an example of the typical land patterns based
on the guidelines given previously. For more detailed layout
guidelines for a complete CPU voltage regulator subsystem,
refer to the ADP3188 data sheet.
