10 Layout

10.1 Layout Guidelines

The PCB layout is an important step to maintain the high performance of the TPS63024x devices.

  • Place input and output capacitors as close as possible to the IC. Traces need to be kept short. Routing wide and direct traces to the input and output capacitor results in low trace resistance and low parasitic inductance.
  • Use a common-power GND.
  • The sense trace connected to FB is signal trace. Keep these traces away from L1 and L2 nodes.
