S upply Connec tions and Layout
The MAX1664 performs both precision analog and
high-power switching functions. Carefully plan supply
connections, bypassing, and layout. Bypass IN and INP
with a 33
isolation resistor (R9, Figure 4) between
them. In addition, sufficient low-ESR bypassing must be
provided on the INP bus to ensure stability of DC-DC 1.
A solid ground plane under the power components,
with a separate ground plane under the analog nodes,
is highly recommended. These ground planes should
be connected at a single, quiet point. Analog reference
and feedback signals should be referred to and routed
over the analog ground plane. Figure 7 shows a typical
layout using separate ground planes.
