TPS54521RHLR Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the TPS54521RHLR is 42V, but it's recommended to keep it below 40V for reliable operation.
  • To ensure the stability of the output voltage, it's essential to use the recommended output capacitor (Cout) value and type, and to follow the layout guidelines provided in the datasheet.
  • The minimum input capacitance required for the TPS54521RHLR is 10uF, but it's recommended to use a higher value (e.g., 22uF) for better performance and stability.
  • The TPS54521RHLR is rated for operation up to 125°C, but it's essential to consider the thermal design and ensure that the device does not exceed the maximum junction temperature (TJ) of 150°C.
  • The output voltage of the TPS54521RHLR can be calculated using the formula: Vout = 0.8V x (1 + R1/R2), where R1 and R2 are the resistors used in the feedback network.
