LM2575HVS-ADJ Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LM2575HVS-ADJ?
  The maximum input voltage that can be applied to the LM2575HVS-ADJ is 60V, but it's recommended to keep it below 50V for reliable operation.
• How do I ensure the output voltage is stable and regulated?
  To ensure a stable and regulated output voltage, make sure to use a suitable output capacitor (e.g., 10uF to 22uF) and a minimum load current of 10mA. Also, ensure the input voltage is within the recommended range.
• What is the minimum input voltage required for the LM2575HVS-ADJ to operate?
  The minimum input voltage required for the LM2575HVS-ADJ to operate is 7V, but it's recommended to keep it above 8V for reliable operation.
• Can I use the LM2575HVS-ADJ in a high-temperature environment?
  The LM2575HVS-ADJ 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 adjust the output voltage of the LM2575HVS-ADJ?
  The output voltage of the LM2575HVS-ADJ can be adjusted by using a resistive divider network between the output and the ADJ pin. The output voltage is determined by the ratio of the resistors and the internal reference voltage (1.23V).
