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
2. Split the ground connections. Use separate planes for the
3. The VCC bypass capacitor should be located as close as

Typical Application Circuit
The circuit in Figure 16 shows how the ADP3410 can be com-
bined with the ADP3421 to form a total power conversion solution
for a microprocessor. The combination provides the supply
voltages for the core processor, the I/O interface, and the clock.
