TPS54312PWP datasheet by Texas Instruments

TPS54312PWP Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS54312PWP?
  The maximum input voltage that can be applied to the TPS54312PWP is 42V, but it's recommended to keep it below 40V for reliable operation.
• How do I ensure the TPS54312PWP is stable and doesn't oscillate?
  To ensure stability, make sure to follow the recommended layout and component selection guidelines in the datasheet, and use a minimum output capacitance of 10uF with an ESR of 10mΩ or less.
• What is the minimum input capacitance required for the TPS54312PWP?
  The minimum input capacitance required is 10uF, but it's recommended to use a higher value (e.g., 22uF) for better input filtering and noise reduction.
• Can I use the TPS54312PWP in a high-temperature environment?
  Yes, the TPS54312PWP is rated for operation up to 125°C, but the maximum junction temperature (TJ) should not exceed 150°C. Ensure proper thermal design and heat sinking to maintain a safe operating temperature.
• How do I adjust the output voltage of the TPS54312PWP?
  The output voltage can be adjusted by changing the resistor divider ratio (R1 and R2) connected to the FB pin. Use the formula in the datasheet to calculate the required resistor values for the desired output voltage.
