6.3 Inductor

  • Keep the inductor connection to the switch node (SW) short.
  • Do not route any digital lines underneath or close to the inductor.
  • Keep the switch node (SW) away from the feedback (FB) pin.
  • The CS pin should be connected directly to the SW pin to accurately sense the voltage across the low-side MOSFET.
  • To minimize noise, place a ground plane underneath the inductor.
