TPS54315PWP datasheet by Texas Instruments

TPS54315PWP Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS54315PWP?
  The maximum input voltage that can be applied to the TPS54315PWP is 42V, but it's recommended to keep it below 40V for reliable operation.
• How do I ensure the TPS54315PWP is stable and doesn't oscillate?
  To ensure stability, make sure to follow the recommended layout and component selection guidelines in the datasheet, and add a 10uF ceramic capacitor between VIN and GND, and a 22uF ceramic capacitor between VOUT and GND.
• What is the minimum input voltage required for the TPS54315PWP to operate?
  The minimum input voltage required for the TPS54315PWP to operate is 6.5V, but it's recommended to keep it above 7V for reliable operation.
• Can I use the TPS54315PWP in a high-temperature environment?
  Yes, the TPS54315PWP can operate in high-temperature environments up to 125°C, but the output current may need to be derated to prevent overheating.
• How do I adjust the output voltage of the TPS54315PWP?
  The output voltage of the TPS54315PWP can be adjusted by changing the resistor divider ratio between the FB pin and the output voltage, as described in the datasheet.
