Printed Circuit Board Layout Considerations
Use the following general guidelines when designing printed
circuit boards:
1.
2.
3.
Trace out the high-current paths and use short, wide traces
to make these connections.
Connect the PGND pin of the ADP3413 as close as pos-
sible to the source of the lower MOSFET.
The VCC bypass capacitor should be located as close as
possible to VCC and PGND pins.

Typical Application Circuits
The circuit in Figure 4 shows how two drivers can be com-
bined with the ADP3160 to form a total power conversion
solution for V
computer. Figure 5 gives a similar application circuit for a
45 A AMD processor.
