TPS40200DR datasheet by Texas Instruments

TPS40200DR Frequently Asked Questions (FAQs)

• What is the recommended input capacitor value for the TPS40200DR?
  The recommended input capacitor value is 10uF to 22uF, with an ESR of 0.1 ohms or less, to ensure stability and reduce output voltage ripple.
• How do I choose the right output capacitor for the TPS40200DR?
  Choose an output capacitor with a value of 10uF to 47uF, with an ESR of 0.1 ohms or less, and a voltage rating of at least 2x the output voltage. X5R or X7R ceramic capacitors are recommended.
• What is the maximum input voltage that the TPS40200DR can handle?
  The TPS40200DR can handle input voltages up to 18V, but it's recommended to keep the input voltage below 15V to ensure reliable operation and minimize power dissipation.
• Can I use the TPS40200DR in a high-temperature environment?
  The TPS40200DR is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage at high temperatures to ensure reliable operation and minimize power dissipation.
• How do I ensure the TPS40200DR is stable and doesn't oscillate?
  Ensure that the input and output capacitors meet the recommended specifications, and that the PCB layout is designed to minimize parasitic inductance and capacitance. Also, avoid using long, thin traces for the power lines.
