TPS5410DR datasheet by Texas Instruments

TPS5410DR Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the TPS5410DR can handle?
  The TPS5410DR can handle input voltages up to 60V, but it's recommended to keep it below 40V for optimal performance and reliability.
• How do I choose the right inductor value for my design?
  The inductor value depends on the output voltage, output current, and switching frequency. A good starting point is to use the inductor value calculation formula provided in the datasheet, and then adjust based on the specific design requirements.
• What is the purpose of the EN pin, and how do I use it?
  The EN (enable) pin is used to turn the converter on and off. It's an active-high input, so connect it to a logic high (e.g., VCC) to enable the converter, and connect it to a logic low (e.g., GND) to disable it.
• How do I compensate for the internal voltage reference tolerance?
  The internal voltage reference has a tolerance of ±1.5%. To compensate for this, you can adjust the feedback resistors (R1 and R2) to achieve the desired output voltage. You can also use an external voltage reference if tighter tolerance is required.
• What is the recommended layout and thermal design for the TPS5410DR?
  Keep the input and output capacitors close to the IC, and use a solid ground plane to reduce noise and improve thermal performance. Use thermal vias to connect the IC's thermal pad to the ground plane, and ensure good airflow around the IC.
