Suggested Layout (DFN)

APPLICATIONS INFORMATION
Board Layout Considerations
As with all switching regulators, careful attention must
be given to the PCB board layout and component place-
ment. Proper layout of the high frequency switching path
is essential. The voltage signals of the SW and D pins
have sharp rising and falling edges. Minimize the length
and area of all traces connected to the SW and D pins.
In particular, it is desirable to minimize the trace length
to and from the flying capacitor, since current in this ca-
pacitor switches directions within a cycle. Always use a
ground plane under the switching regulator to minimize
interplane coupling.
