10.1.2 Power Supply Layout Guidelines

The following filtering circuits are recommended for the power supply inputs listed below.

  • VAD115_VX1
  • VAD18_VX1
  • VAD115_FPD
  • VDD33_FPD
  • VAD33_USB
  • VDD18_SCS

Since the PBC layout is critical to the performance of the interfaces associated with these power supplies, it is vital that these power supplies be treated like an analog signal. Specifically:

  • Place high-frequency components (such as ferrites and capacitors) as close to the power ball(s) as possible.
  • Choose high-frequency ceramic capacitors (such as those with a valua of 0.1 µF, 0.01 µF, and 100 nF) that have low ESR and ESL values. Design the leads as short as possible, and as such, it is recommended that these capacitors be placed under the package on the opposite side of the board..
  • For each power pin, a single trace (as wide as possible) must be used from the controller to the capacitor and then through the series ferrite to the power source.
  • For each power pin, add a 100-nF decoupling capacitor placed near the escape via. Add this decoupling capacitance to the capacitance recommended for filters. These are minimum recommendations, so different layouts could require additional capacitance.
  • See Table 10-1 for the recommended series ferrite component for these supplies.
