For high efficiency, good regulation, and stability, a well-
designed printed circuit board layout is required.
Use the following guidelines when designing printed circuit
boards (also see Figure 24 for a block diagram and Figure 2 for
a pin configuration).

Keep the low ESR input capacitor, C
GND. This minimizes noise injected into the part from
board parasitic inductance.
Keep the high current path from C
inductor to SW as short as possible.
Place the feedback resistors, R1 and R2, as close to FB as
possible to prevent noise pickup. Connect the ground of
the feedback network directly to an AGND plane that
makes a Kelvin connection to the GND pin.
Avoid routing high impedance traces from feedback
resistors near any node connected to SW or near the
inductor to prevent radiated noise injection.
Keep the low ESR output capacitor, C
and GND. This minimizes noise injected into the part from
board parasitic inductance.
Connect Pin 7 (EPAD) and GND to a large copper plane
for proper heat dissipation.
