Designing a PC Board
Good PC board layout is important to achieve optimal
performance from the MAX1565. Poor design can
cause excessive conducted and/or radiated noise.
Conductors carrying discontinuous currents, and any
high-current path should be made as short and wide as
possible. A separate low-noise ground plane containing
the reference and signal grounds should connect to the
power-ground plane at only one point to minimize the
effects of power-ground currents. Typically, the ground
planes are best joined right at the IC.
Keep the voltage feedback network very close to the
IC, preferably within 0.2in (5mm) of the FB_ pin. Nodes
with high dV/dt (switching nodes) should be kept as
small as possible and should be routed away from
high-impedance nodes such as FB_. Refer to the
MAX1565EVKIT evaluation kit data sheet for a full PC
board example.
