TPS54312PWPG4 datasheet by Texas Instruments

TPS54312PWPG4 Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS54312PWPG4?
  The maximum input voltage that can be applied to the TPS54312PWPG4 is 42V, but it's recommended to keep it below 40V for reliable operation.
• How do I ensure the TPS54312PWPG4 is stable and doesn't oscillate?
  To ensure stability, make sure to follow the recommended layout guidelines, use a sufficient output capacitor, and add a compensation network (Rc and Cc) as described in the datasheet.
• What is the minimum input voltage required for the TPS54312PWPG4 to operate?
  The minimum input voltage required for the TPS54312PWPG4 to operate is 6.5V, but it's recommended to keep it above 7V for reliable startup and operation.
• Can I use the TPS54312PWPG4 in a high-temperature environment?
  The TPS54312PWPG4 is rated for operation up to 150°C, but it's recommended to derate the output current and input voltage as temperature increases to ensure reliable operation.
• How do I calculate the output voltage of the TPS54312PWPG4?
  The output voltage of the TPS54312PWPG4 can be calculated using the formula: Vout = (R1 / R2) * 0.8V, where R1 and R2 are the resistors used in the feedback network.
