11.1 Layout Guidelines

Follow these guidelines to lay out the printed-circuit-board (PCB) that is used for the TPS389x family of devices.

  • Place the VCC decoupling capacitor close to the device.
  • Avoid using long traces for the VCC supply node. The VCC capacitor (CVCC), along with parasitic inductance from the supply to the capacitor, can form an LC tank and create ringing with peak voltages above the maximum VCC voltage.
