Layout Considerations
TPS63700
SLVS530–SEPTEMBER 2005
Compensation Capacitor
The control loop of the converter is completely compensated internally. However the internal feedforward system
requires an external capacitor. A 4.7-nF capacitor at the COMP pin of the converter is recommended.
For all switching power supplies the layout is an important step in the design, especially at high peak currents
and high switching frequencies. If the layout is not carefully done, the regulator could show stability problems as
well as EMI problems. Therefore, use wide and short traces for the main current paths, and for the power-ground
tracks. The input capacitors, output capacitors, the inductors, and the rectifying diodes should be placed as close
as possible to the IC to keep parasitic inductances low.
The feedback divider should be placed as close as possible to the VREF pin of the IC. Use short traces when
laying out the control ground.
