TPS54873PWP Frequently Asked Questions (FAQs)

  • A good PCB layout for the TPS54873PWP involves placing the input and output capacitors close to the device, using a solid ground plane, and minimizing the length of the input and output traces. Additionally, it's recommended to use a 4-layer PCB with a dedicated power plane and a dedicated ground plane.
  • The input capacitor should have a low ESR and be rated for the input voltage. A ceramic capacitor with an X7R or X5R dielectric is recommended. The output capacitor should have a low ESR and be rated for the output voltage. A ceramic capacitor with an X7R or X5R dielectric is recommended. The capacitance value should be at least 10uF for the input and 22uF for the output.
  • The maximum ambient temperature range for the TPS54873PWP is -40°C to 125°C. However, the device can operate up to 150°C with derating.
  • The power dissipation of the TPS54873PWP can be calculated using the formula: Pd = (Vin - Vout) x Iout x Efficiency. The efficiency of the device can be found in the datasheet.
  • The recommended input voltage range for the TPS54873PWP is 2.7V to 5.5V. However, the device can operate with an input voltage as low as 2.5V with reduced performance.
