TPS65263-1QRHBRQ1 Frequently Asked Questions (FAQs)

  • A good PCB layout for the TPS65263-1QRHBRQ1 involves placing the input capacitors close to the VIN pin, using a solid ground plane, and keeping the high-current paths short and wide. TI provides a recommended layout in the datasheet and in application notes.
  • Choose output capacitors with a low ESR (Equivalent Series Resistance) and a high ripple current rating. The recommended output capacitance is 10uF to 22uF, with a voltage rating of at least 2x the output voltage. X5R or X7R ceramic capacitors are good options.
  • The TPS65263-1QRHBRQ1 can handle input voltages up to 18V, but it's recommended to keep the input voltage below 15V to ensure reliable operation and to prevent overheating.
  • The output voltage of the TPS65263-1QRHBRQ1 can be adjusted by connecting a resistor divider network between the FB pin and the output voltage. The datasheet provides a formula to calculate the required resistor values.
  • The TPS65263-1QRHBRQ1 has a thermal derating of 2.5% per degree Celsius above 25°C. This means that the maximum output current decreases as the ambient temperature increases.
