Typical Application Circuit (Figure 1), should be as
short and wide as possible. Additionally, the current
loops formed by the power components (CIN, COUT,
L1, and D1) should be as short as possible to avoid
radiated noise. Connect the ground pins of these
power components at a common node in a star-ground
configuration. Separate the noisy traces, such as the
LX node, from the feedback network with grounded
copper. Furthermore, keep the extra copper on the
board and integrate it into a pseudo-ground plane.
When using external feedback, place the resistors as
close to the feedback pin as possible to minimize noise
coupling.
