TPS65400RGZR Frequently Asked Questions (FAQs)

  • A good PCB layout is crucial for the TPS65400RGZR. Ensure a solid ground plane, keep the input and output capacitors close to the IC, and use a star-connection for the input voltage to minimize noise and EMI.
  • Choose X5R or X7R ceramic capacitors with a voltage rating of at least 2x the input voltage. For the output capacitor, select a capacitor with a low ESR (Equivalent Series Resistance) and a voltage rating of at least 1.5x the output voltage.
  • The maximum input voltage is 18V, but it's recommended to keep it below 15V to ensure reliable operation and minimize the risk of damage.
  • The TPS65400RGZR is rated for operation up to 125°C, but it's essential to consider the thermal design and ensure proper heat dissipation to prevent overheating.
  • The soft-start feature can be configured by connecting a capacitor between the SS pin and GND. The capacitor value determines the soft-start time, with larger values resulting in slower start-up times.
