TPS54314PWPR Frequently Asked Questions (FAQ)
-
The maximum input voltage that can be applied to the TPS54314PWPR is 42V, but it's recommended to keep it below 40V for reliable operation.
-
The inductor value depends on the output voltage, output current, and switching frequency. A good starting point is to use the inductor selection guide in the datasheet or use an online inductor selection tool.
-
The EN (enable) pin is used to turn the converter on and off. It's an active-high input, so connect it to VIN or a logic high signal to enable the converter, and connect it to GND or a logic low signal to disable it.
-
The TPS54314PWPR is a voltage-mode regulator, and compensation is required for stability. Use the compensation network shown in the datasheet, and adjust the values based on your specific design requirements.
-
The maximum output current that the TPS54314PWPR can deliver is 3A, but it's recommended to derate the output current based on the ambient temperature and the input voltage.
