5.8 PCB Layout Information
Good printed circuit board layout techniques are
important to any switching circuitry and switching
power supplies are no different. When wiring the high
current paths, short and wide traces should be used.
This high current path is shown with red connections in
Therefore, it is important that the components along the
high current path should be placed as close as possible
to the MCP1603 to minimize the loop area.
The feedback resistors and feedback signal should be
routed away from the switching node and this switching
current loop. When possible ground planes and traces
should be used to help shield the feedback signal and
minimize noise and magnetic interference.
