The maximum input voltage that can be applied to the TPS54225PWPR is 18V, but it's recommended to keep it below 15V for optimal performance and reliability.
To ensure the stability of the output voltage, make sure 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 TPS54225PWPR is 10uF, but it's recommended to use a higher value (22uF or more) for better performance and stability.
The TPS54225PWPR is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage at high temperatures to ensure reliability and prevent overheating.
The output voltage of the TPS54225PWPR can be calculated using the formula: Vout = (R1 / R2) * (1.21V), where R1 and R2 are the resistors connected to the FB pin.
