TPS51285ARUKR Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the input and output capacitors close to the IC, and use short, wide traces for the power paths.
  • Ensure that the output capacitor has a low ESR, and the input capacitor has a high capacitance. Also, add a small ceramic capacitor (e.g., 10nF) between the VCC and GND pins to filter high-frequency noise.
  • Although the datasheet specifies a maximum input voltage of 5.5V, it's recommended to limit the input voltage to 5V to ensure reliable operation and prevent damage to the IC.
  • While the datasheet recommends a specific inductor value and type, you can use a different inductor as long as it meets the required inductance and current rating. However, this may affect the converter's performance and efficiency.
  • The output voltage can be adjusted by changing the resistor divider ratio (R1 and R2) connected to the FB pin. Use the formula in the datasheet to calculate the required resistor values for the desired output voltage.
