TPS54973PWPR Frequently Asked Questions (FAQ)
-
The maximum input voltage that can be applied to the TPS54973PWPR is 18V, but it's recommended to keep it below 15V for optimal performance and reliability.
-
To ensure stability, make sure to follow the recommended layout and component selection guidelines in the datasheet, and add a 10uF ceramic capacitor between the VIN and GND pins. Also, keep the output capacitor ESR below 10mΩ.
-
The minimum output voltage that can be set using the FB pin is 0.8V, but it's recommended to keep it above 1V for optimal performance and accuracy.
-
The output voltage can be calculated using the formula: Vout = 0.8V x (1 + R2/R1). Make sure to choose R1 and R2 values that result in a stable and accurate output voltage.
-
The maximum output current that the TPS54973PWPR can deliver is 3A, but it's recommended to keep it below 2.5A for optimal performance and reliability.
