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 (VIN and L1-16) away from the switching nodes.

Place COUT1-16 and CIN close to the VIN pins. Always use

a ground plane under the switching regulator to minimize

interplane coupling. Recommended component placement

is shown in Figures 4-7.
