The maximum input voltage that can be applied to the TPS542941RSAR is 42V, but it's recommended to keep it below 40V for reliable operation.
To ensure the stability of the output voltage, make sure to use a suitable output capacitor with a low ESR (Equivalent Series Resistance) and a sufficient capacitance value, as recommended in the datasheet.
The minimum input capacitance required for the TPS542941RSAR is 10uF, but it's recommended to use a higher value (e.g., 22uF) for better performance and stability.
The TPS542941RSAR is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage at higher temperatures to ensure reliable operation.
The output voltage of the TPS542941RSAR can be calculated using the formula: Vout = (R1 / R2) * (Vref), where R1 and R2 are the resistors in the feedback network, and Vref is the internal reference voltage (1.21V).
