TPS54140ADRCR datasheet by Texas Instruments

TPS54140ADRCR Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS54140ADRCR?
  The maximum input voltage that can be applied to the TPS54140ADRCR is 60V, but it's recommended to operate within the specified input voltage range of 4.5V to 40V for optimal performance and reliability.
• How do I ensure the stability of the output voltage?
  To ensure the stability of the output voltage, it's essential to follow the recommended layout and component selection guidelines provided in the datasheet, including the use of a suitable output capacitor and a low-ESR input capacitor.
• What is the maximum output current that the TPS54140ADRCR can deliver?
  The TPS54140ADRCR can deliver up to 4A of output current, but the actual output current capability may be limited by the input voltage, output voltage, and thermal considerations.
• How do I adjust the output voltage of the TPS54140ADRCR?
  The output voltage of the TPS54140ADRCR can be adjusted by using a resistor divider network between the output voltage sense pin (FB) and the output voltage pin (VOUT). The datasheet provides a formula to calculate the required resistor values.
• What is the purpose of the enable pin (EN) on the TPS54140ADRCR?
  The enable pin (EN) is used to turn the regulator on or off. When the EN pin is pulled high, the regulator is enabled, and when it's pulled low, the regulator is disabled.
