TPS54040DGQR Frequently Asked Questions (FAQ)
-
The maximum input voltage that can be applied to the TPS54040DGQR is 42V, but it's recommended to keep it below 40V for reliable operation.
-
To ensure the stability of the output voltage, it's essential 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 TPS54040DGQR is 1uF, but it's recommended to use a 4.7uF to 10uF ceramic capacitor to ensure stable operation.
-
The TPS54040DGQR is rated for operation up to 125°C, but it's essential to consider the thermal design and ensure that the junction temperature (TJ) does not exceed 150°C.
-
The output voltage of the TPS54040DGQR can be calculated using the formula: Vout = 0.8V x (1 + R2/R1), where R1 and R2 are the resistors used in the feedback network.
