TPS61251DSGR Frequently Asked Questions (FAQs)

  • The recommended input capacitor value is 10uF to 22uF, with an ESR of 100mΩ or less, to ensure stability and optimal performance.
  • Choose an output capacitor with a capacitance value between 10uF to 47uF, and an ESR of 100mΩ or less. The output capacitor should be rated for the output voltage and have a low ESL to minimize ringing.
  • The TPS61251DSGR can handle a maximum input voltage of 15V, but it's recommended to keep the input voltage below 12V for optimal performance and reliability.
  • Ensure good thermal conduction by mounting the device on a PCB with a solid copper plane, and provide adequate airflow. Keep the junction temperature below 125°C to ensure reliable operation.
  • The TPS61251DSGR is rated for operation up to 85°C ambient temperature. For higher temperatures, consider using a heat sink or a thermally-enhanced package, and ensure the device is properly derated.
