TPS54310PWP datasheet by Texas Instruments

TPS54310PWP Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS54310PWP?
  The maximum input voltage that can be applied to the TPS54310PWP is 42V, but it's recommended to keep it below 40V for reliable operation.
• How do I choose the right inductor value for my design?
  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 TI's WEBENCH Power Designer tool to get a recommended inductor value.
• What is the purpose of the EN pin, and how do I use it?
  The EN (enable) pin is used to turn the converter on and off. It's an active-high input, so connect it to a logic high (e.g., VCC) to enable the converter, and connect it to a logic low (e.g., GND) to disable it.
• How do I compensate the voltage regulator loop?
  The TPS54310PWP has a type-III compensation network. Use the compensation component values provided in the datasheet, or use TI's Power Stage Designer tool to generate a custom compensation network based on your specific design requirements.
• What is the maximum output current that the TPS54310PWP can deliver?
  The maximum output current that the TPS54310PWP can deliver is 3A, but it's recommended to derate the output current based on the ambient temperature and the PCB's thermal design.
