8.4.1 Layout Guidelines

Follow these guidelines for laying out the printed circuit board (PCB) that is used for the TPS3423 and TPS3424.

  • Make sure that the connection to the VDD pin is low impedance. Good analog design practice recommends placing a 0.1µF ceramic capacitor as near as possible to the VDD pin.
  • Place the external capacitor on close to LPT and SPT pin for TPS3424.
  • Parasitic on LPT and SPT must be less than 50pF when these pins are floating for TPS3424.
