TPS56428RHLT Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the TPS56428RHLT is 18V, but it's recommended to keep it below 15V for optimal performance and reliability.
  • To ensure the stability of the output voltage, it's essential to follow the recommended layout and component selection guidelines provided in the datasheet, and to use a sufficient output capacitor with a low ESR (Equivalent Series Resistance).
  • The minimum input capacitance required for the TPS56428RHLT is 10uF, but it's recommended to use a higher value (e.g., 22uF) for better performance and stability.
  • The TPS56428RHLT is rated for operation up to 125°C, but it's essential to consider the thermal design and ensure that the device is properly cooled to prevent overheating and ensure reliable operation.
  • The output voltage of the TPS56428RHLT can be calculated using the formula: Vout = (R1/R2) * (Vref), where R1 and R2 are the resistors connected to the FB pin, and Vref is the internal reference voltage (0.8V).
