TPS53681RSBR Frequently Asked Questions (FAQs)

  • A good PCB layout for the TPS53681RSBR involves placing the input capacitors close to the VIN pin, using a solid ground plane, and keeping the high-current paths short and wide. A 4-layer PCB with a dedicated power plane and a solid ground plane is recommended.
  • Choose input capacitors with low ESR and high ripple current rating. For output capacitors, choose ones with low ESR and high capacitance. The recommended capacitance values are 10uF to 22uF for the input capacitor and 22uF to 47uF for the output capacitor.
  • The maximum ambient temperature range for the TPS53681RSBR is -40°C to 125°C. However, the device can operate up to 150°C with derating.
  • The TPS53681RSBR has a built-in overcurrent protection feature. To implement it, connect a resistor (RILIM) between the ILIM pin and the GND pin. The value of RILIM determines the overcurrent threshold.
  • Yes, the TPS53681RSBR is suitable for high-reliability applications. It is qualified to automotive and industrial standards, and it has a high MTBF (mean time between failures) rating.
