The maximum input voltage that can be applied to the TPS54120RGYT is 42V, but it's recommended to keep it below 40V for reliable operation.
To ensure stability, make sure to follow the recommended layout and component selection guidelines in the datasheet, and add a 10uF ceramic capacitor between VIN and GND, and a 1uF ceramic capacitor between VOUT and GND.
The minimum input voltage required for the TPS54120RGYT to operate is 4.5V, but it's recommended to keep it above 5V for reliable operation.
Yes, the TPS54120RGYT can operate in high-temperature environments up to 125°C, but the output current may need to be derated to prevent overheating.
The output voltage of the TPS54120RGYT can be adjusted by changing the resistor divider ratio between the FB pin and the output voltage, as described in the datasheet.
