TPS5403DR Frequently Asked Questions (FAQs)

  • The TPS5403DR can handle input voltages up to 60V, but it's recommended to keep it below 50V for reliable operation.
  • The inductor value depends on the output voltage, output current, and switching frequency. A good starting point is to use the inductor selection guide in the datasheet or use an online inductor calculator.
  • The EN (enable) pin is used to turn the converter on and off. It's an active-high input, so connect it to VIN or a logic high signal to enable the converter, and connect it to GND or a logic low signal to disable it.
  • The internal voltage reference has a tolerance of ±1.5%. To compensate for this, you can adjust the output voltage by adjusting the feedback resistors (R1 and R2) or by using an external voltage reference.
  • The TPS5403DR can deliver up to 3A of output current, but this depends on the input voltage, output voltage, and thermal conditions. Make sure to check the thermal derating curves in the datasheet.
