Connect GND to the ground plane. The external feed-

back network should be very close to the FB pin, within

0.2in (5mm). Keep noisy traces, such as the LX node,

as short as possible. Connect GND to the exposed

paddle directly under the IC. Figure 8 and the

MAX8620Y evaluation kit illustrate examples of PC

board layout and routing schemes.
