Layout
The MAX877/MAX878/MAX879’s high peak currents
and high-frequency operation make PC layout impor-
tant for minimum ground bounce and noise. Locate
input bypass and output filter capacitors close to the
device pins. All connections to the FB pin (MAX879)
should also be kept as short as possible. A ground
plane is recommended. Solder AGND (pin 3) and
PGND (pin 4) directly to the ground plane. Refer to the
MAX877/MAX878/MAX879 evaluation kit (EV kit) manu-
al for a suggested surface-mount layout.
