TPS68470YFFT Frequently Asked Questions (FAQs)

  • A good PCB layout for the TPS68470YFFT involves keeping the input and output capacitors close to the device, using a solid ground plane, and minimizing the length of the input and output traces. A 4-layer PCB with a dedicated power plane and a solid ground plane is recommended.
  • To ensure the stability of the TPS68470YFFT output voltage, it is recommended to use a minimum output capacitance of 10uF, and to place the output capacitor close to the device. Additionally, the output voltage can be stabilized by adding a 10nF capacitor in parallel with the output capacitor.
  • The TPS68470YFFT can handle a maximum input voltage of 5.5V. Exceeding this voltage may damage the device.
  • The TPS68470YFFT output voltage can be programmed using the FB pin. A resistive divider network can be used to set the desired output voltage. The FB pin voltage is 0.6V, and the output voltage can be calculated using the formula: Vout = 0.6V x (R1 + R2) / R2.
  • The TPS68470YFFT has a thermal derating of 12.5mW/°C above 25°C. This means that the device's power dissipation must be reduced as the temperature increases to prevent overheating.
