TPS65279RHHR Frequently Asked Questions (FAQs)

  • A good PCB layout for the TPS65279RHHR 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.
  • The output voltage of the TPS65279RHHR can be set using resistors R1 and R2. Use the formula in the datasheet to calculate the required resistor values for your desired output voltage. You can also use TI's online voltage regulator calculator tool to simplify the process.
  • The TPS65279RHHR can handle input voltages up to 18V, but it's recommended to keep the input voltage below 15V for optimal performance and to prevent overheating.
  • To ensure stability, make sure to use the recommended output capacitor values and types, and keep the output capacitor close to the VOUT pin. Also, avoid using long, thin traces for the output voltage, as they can cause oscillations.
  • The TPS65279RHHR is rated for operation up to 125°C, but its performance may degrade at high temperatures. Make sure to derate the output current and input voltage according to the datasheet's thermal derating curves.
