TPS542951RSAT datasheet by Texas Instruments

TPS542951RSAT Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS542951RSAT?
  The maximum input voltage that can be applied to the TPS542951RSAT is 42V, but it's recommended to keep it below 40V for reliable operation.
• How do I ensure the TPS542951RSAT is stable and doesn't oscillate?
  To ensure stability, make sure to follow the recommended layout guidelines, use a sufficient output capacitor (at least 10uF), and add a 1nF to 10nF capacitor between the VIN and EN pins to filter noise.
• What is the minimum input voltage required for the TPS542951RSAT to operate?
  The minimum input voltage required for the TPS542951RSAT to operate is 4.5V, but it's recommended to keep it above 5V for reliable startup and operation.
• Can I use the TPS542951RSAT in a high-temperature environment?
  The TPS542951RSAT is rated for operation up to 125°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 TPS542951RSAT?
  The output voltage of the TPS542951RSAT can be calculated using the formula: VOUT = 0.8V x (1 + RFBT/RFB), where RFBT and RFB are the feedback resistors.
