Bypass Considerations
Bypass IN and OUT to PGND with 10μF and 47μF,
respectively. Bypass BP and REF to GND with 0.1μF
and 0.22μF, respectively. Locate the bypass capacitors
as close as possible to their respective pins to minimize
noise coupling. For optimum performance, place input
and output capacitors as close to the device as feasi-
ble (see Capacitor Selection section).
PC Board Layout and Routing
High switching frequencies and large peak currents
make PC board layout a very important part of design.
Good design minimizes excessive EMI on the feedback
paths and voltage gradients in the ground plane, both
Table 1. Suggested Inductors
of which can result in instability or regulation errors.
Connect the inductor, input filter capacitor, and output
filter capacitor as close together as possible, and keep
their traces short, direct, and wide. Connect their
ground pins at a single common node in a star-ground
configuration. The external voltage-feedback network
should be very close to the FB pin, within 0.2in (5mm).
Keep noisy traces, such as from the LX pin, away from
the voltage-feedback network; also keep them sepa-
rate, using grounded copper. Connect GND and PGND
at the highest quality ground. The MAX1692 evaluation
kit manual illustrates an example PC board layout and
routing scheme.
