TPS54334DDA Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the TPS54334DDA 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 TI's WEBENCH Power Designer tool to get a recommended inductor value.
  • 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 TPS54334DDA has a type-III compensation network. Use the compensation component values provided in the datasheet or use TI's Power Stage Designer tool to get a recommended compensation network.
  • The maximum output current that the TPS54334DDA can deliver is 3.5A, but it's recommended to derate the output current based on the ambient temperature and the PCB thermal design.
