TPS5124DBTR datasheet by Texas Instruments

TPS5124DBTR Frequently Asked Questions (FAQs)

• What is the recommended input capacitor value for the TPS5124DBTR?
  The recommended input capacitor value is 10uF to 22uF, with a voltage rating of at least 6.3V. This ensures stable operation and reduces input ripple.
• How do I calculate the output voltage of the TPS5124DBTR?
  The output voltage (Vout) can be calculated using the formula: Vout = (R1 / R2) * (1.25V), where R1 and R2 are the resistors connected to the FB pin. The recommended ratio of R1 to R2 is between 1:1 and 10:1.
• What is the maximum input voltage that the TPS5124DBTR can handle?
  The maximum input voltage rating for the TPS5124DBTR is 18V. Exceeding this voltage may damage the device or affect its performance.
• Can I use the TPS5124DBTR in a high-temperature environment?
  The TPS5124DBTR is rated for operation up to 125°C (TJ). However, it's essential to ensure proper thermal design and heat dissipation to prevent overheating, especially in high-temperature applications.
• How do I ensure the TPS5124DBTR is stable and doesn't oscillate?
  To ensure stability, follow the recommended PCB layout guidelines, use a low-ESR output capacitor, and add a 10nF to 100nF capacitor between the Vout and GND pins. Additionally, avoid long traces and minimize parasitic inductance.
