TPS2045DR Frequently Asked Questions (FAQs)

  • The TPS2045DR can handle input voltages up to 40V, but it's recommended to keep it below 30V for optimal performance and reliability.
  • To ensure stability, make sure to follow the recommended PCB layout guidelines, use a sufficient output capacitor (at least 10uF), and add a 1uF capacitor between the VIN and EN pins.
  • The TPS2045DR can operate with input voltages as low as 2.5V, but the output voltage regulation may not be guaranteed below 3.5V.
  • The TPS2045DR is rated for operation up to 125°C, but its performance and reliability may degrade above 85°C. Ensure proper thermal management and consider derating the output current at high temperatures.
  • The output voltage of the TPS2045DR is set by the resistive divider network between the FB pin and the output voltage. Use the formula: Vout = 0.6V x (R1 + R2) / R2, where R1 and R2 are the resistors in the divider network.
