POWER MANAGEMENT
Applications Information (Cont.)
PCB Layout Considerations
Poor layout can degrade the performance of the DC-DC
converter and can contribute to EMI problems, ground
bounce and resistive voltage losses. Poor regulation and
instability can result.
A few simple design rules can be implemented to ensure
good layout:
1. Place the inductor and ? lter capacitors as close to the
device as possible and use short wide traces between
the power components.

PRELIMINARY
2. Route the output voltage feedback path away from the
inductor and LX node to minimize noise and magnetic
interference. Keep R FB1 and R FB2 close to the ADJ pin
to avoid noise pickup.
3. Maximize ground metal on the component side to
improve the return connection and thermal dissipation.
Separation between the LX node and GND should be
maintained to avoid coupling of switching noise to the
ground plane.
4. Use a ground plane with several vias connecting to
the component side ground to further reduce noise
interference on sensitive circuit nodes.
