Layout Guidelines

The PCB layout is an important step to maintain the high performance of the TLV62569A device.

  • The input/output capacitors and the inductor should be placed as close as possible to the IC. This keeps the power traces short. Routing these power traces direct and wide results in low trace resistance and low parasitic inductance.
  • The low side of the input and output capacitors must be connected properly to the power GND to avoid a GND potential shift.
  • The sense traces connected to FB are signal traces. Special care should be taken to avoid noise being induced. Keep these traces away from SW nodes.
  • GND layers might be used for shielding.
