TPS54531DDAR Frequently Asked Questions (FAQ)

  • The maximum input voltage that can be applied to the TPS54531DDAR 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 a suitable output capacitor with a low equivalent series resistance (ESR) and a sufficient capacitance value. A 10uF to 22uF ceramic capacitor is recommended.

  • The minimum input capacitance required for the TPS54531DDAR is 10uF, but it's recommended to use a higher value (22uF or more) for better input voltage filtering and stability.

  • The TPS54531DDAR 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 TPS54531DDAR 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.
