TPS54560BQDDARQ1 datasheet by Texas Instruments

TPS54560BQDDARQ1 Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS54560BQDDARQ1?
  The maximum input voltage 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 an online inductor calculator.
• 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 VIN or a logic high signal to enable the converter, and connect it to GND or a logic low signal to disable it.
• How do I set the output voltage of the TPS54560BQDDARQ1?
  The output voltage is set using the FB (feedback) pin and an external resistor divider network. The datasheet provides a formula to calculate the resistor values based on the desired output voltage.
• What is the maximum output current that the TPS54560BQDDARQ1 can deliver?
  The maximum output current is 5A, but it's limited by the thermal performance of the package and the PCB design. Make sure to check the thermal derating curves in the datasheet.
