TPS5431DDAR Frequently Asked Questions (FAQ)
-
The maximum input voltage that can be applied to the TPS5431DDAR is 42V, but it's recommended to keep it below 40V for reliable operation.
-
To ensure stability, make sure to use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Also, keep the input and output capacitors close to the device and use a low-ESR capacitor for the output.
-
The minimum input voltage required for the TPS5431DDAR to operate is 6.5V, but it's recommended to keep it above 7V for reliable operation.
-
Yes, the TPS5431DDAR can operate in high-temperature environments, but the junction temperature should not exceed 150°C. Make sure to follow the thermal design guidelines and use a suitable heat sink if necessary.
-
The output voltage of the TPS5431DDAR 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 (1.221V).
