TPS54680PWPR datasheet by Texas Instruments

TPS54680PWPR Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS54680PWPR?
  The maximum input voltage that can be applied to the TPS54680PWPR is 6.5V. Exceeding this voltage may damage the device.
• How do I ensure the stability of the output voltage?
  To ensure the stability of the output voltage, it is recommended to use a minimum output capacitance of 10uF with an ESR of 10mΩ or less, and to place the capacitor close to the output pin.
• What is the recommended PCB layout for the TPS54680PWPR?
  A good PCB layout for the TPS54680PWPR involves placing the input capacitor close to the VIN pin, and the output capacitor close to the VOUT pin. It is also recommended to keep the power traces short and wide, and to use a solid ground plane to reduce noise and improve thermal performance.
• How do I calculate the output voltage of the TPS54680PWPR?
  The output voltage of the TPS54680PWPR can be calculated using the following formula: VOUT = 0.8V x (1 + R1/R2), where R1 and R2 are the resistors connected to the FB pin.
• What is the maximum output current that the TPS54680PWPR can deliver?
  The maximum output current that the TPS54680PWPR can deliver is 6A. However, the actual output current may be limited by the input voltage, output voltage, and thermal performance of the device.
