TPS5124DBTR Frequently Asked Questions (FAQs)

  • 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.
  • 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.
  • The maximum input voltage rating for the TPS5124DBTR is 18V. Exceeding this voltage may damage the device or affect its performance.
  • 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.
  • 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.
