LM2574HVM-ADJ datasheet by Texas Instruments

LM2574HVM-ADJ Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LM2574HVM-ADJ?
  The maximum input voltage that can be applied to the LM2574HVM-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 accurate?
  To ensure the output voltage is stable and accurate, make sure to use a stable input voltage, choose the correct output voltage setting resistors, and provide adequate decoupling capacitors at the input and output.
• What is the minimum input voltage required for the LM2574HVM-ADJ to operate?
  The minimum input voltage required for the LM2574HVM-ADJ to operate is around 7V, but it's recommended to keep it above 8V for reliable startup and operation.
• Can I use the LM2574HVM-ADJ in a high-temperature environment?
  The LM2574HVM-ADJ is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage as the temperature increases to ensure reliable operation.
• How do I protect the LM2574HVM-ADJ from input voltage surges and spikes?
  To protect the LM2574HVM-ADJ from input voltage surges and spikes, use a TVS diode or a transient voltage suppressor at the input, and consider adding a fuse or a current limiter to prevent overcurrent conditions.
