Board Layout Considerations
As with all switching regulators, careful attention must be
paid to the PCB board layout and component placement.
To prevent electromagnetic interference (EMI) problems,
proper layout of high frequency switching paths is essential.
Minimize the length and area of all traces connected to
the SW1-16 and PWM1-16 pins. Keep the sense voltage
pins (V
IN
and L1-16) away from the switching nodes.
Place C
OUT1-16
and C
IN
close to the V
IN
pins. Always use
a ground plane under the switching regulator to minimize
interplane coupling. Recommended component placement
is shown in Figures 4-7.
