TPS51716RUKR Frequently Asked Questions (FAQs)

  • A good PCB layout for the TPS51716RUKR 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 application notes.
  • Choose an output capacitor with a low ESR (Equivalent Series Resistance) and a high ripple current rating. A ceramic capacitor with an X5R or X7R dielectric is recommended. The output capacitor value should be at least 10uF, but a larger value may be needed depending on the output voltage and current requirements.
  • The TPS51716RUKR can handle input voltages up to 17V, but the recommended maximum input voltage is 15V to ensure reliable operation and minimize power losses.
  • The output voltage of the TPS51716RUKR can be adjusted by changing the resistor divider ratio between the FB pin and the output voltage. A higher resistor value will increase the output voltage, while a lower value will decrease it.
  • The thermal derating curve for the TPS51716RUKR is provided in the datasheet. The device can operate up to 125°C, but the output current should be derated above 85°C to prevent overheating.
