LM2591HVS-ADJ/NOPB datasheet by Texas Instruments

LM2591HVS-ADJ/NOPB Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LM2591HVS-ADJ/NOPB?
  The maximum input voltage is 40V, but it's recommended to keep it below 35V for reliable operation.
• How do I ensure the output voltage is stable and regulated?
  To ensure a stable output voltage, make sure to use a suitable output capacitor (e.g., 10uF to 22uF) and a feedback resistor (e.g., 1kΩ to 10kΩ) between the output and the adjust pin.
• What is the minimum input voltage required for the LM2591HVS-ADJ/NOPB to operate?
  The minimum input voltage is 7V, but it's recommended to keep it above 8V for reliable operation.
• Can I use the LM2591HVS-ADJ/NOPB in a high-temperature environment?
  The LM2591HVS-ADJ/NOPB is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage at high temperatures to ensure reliable operation.
• How do I calculate the output voltage of the LM2591HVS-ADJ/NOPB?
  The output voltage can be calculated using the formula: Vout = 1.23 * (1 + R2/R1), where R1 and R2 are the feedback resistors.
