TPS65261RHBR Frequently Asked Questions (FAQs)

  • A good PCB layout for the TPS65261RHBR involves placing the input capacitors close to the VIN pin, using a solid ground plane, and keeping the high-current paths short and wide. It's also recommended to use a 4-layer PCB with a dedicated power plane and a dedicated ground plane.
  • The output voltage of the TPS65261RHBR can be set using the FB pin. The recommended output voltage range is 0.9V to 3.3V. To choose the right output voltage, consider the voltage requirements of your load, the input voltage range, and the desired efficiency.
  • The TPS65261RHBR can handle input voltages up to 18V, but it's recommended to keep the input voltage below 15V for optimal performance and reliability.
  • To ensure the stability of the output voltage during startup and shutdown, use a soft-start circuit to limit the inrush current and prevent voltage overshoot. You can also use a capacitor on the EN pin to slow down the startup time.
  • The TPS65261RHBR can deliver up to 3A of output current, but the actual output current depends on the input voltage, output voltage, and thermal conditions. Make sure to check the thermal derating curves in the datasheet to ensure reliable operation.
