LM2574HVMX-ADJ/NOPB datasheet by Texas Instruments

LM2574HVMX-ADJ/NOPB Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LM2574HVMX-ADJ/NOPB?
  The maximum input voltage that can be applied to the LM2574HVMX-ADJ/NOPB is 60V. Exceeding this voltage can cause damage to the device.
• How do I ensure the stability of the output voltage in the LM2574HVMX-ADJ/NOPB?
  To ensure the stability of the output voltage, a minimum output capacitance of 22uF is recommended. Additionally, the output capacitor should have a low ESR (Equivalent Series Resistance) to prevent oscillations.
• What is the maximum output current that the LM2574HVMX-ADJ/NOPB can provide?
  The maximum output current that the LM2574HVMX-ADJ/NOPB can provide is 3A. Exceeding this current can cause overheating and damage to the device.
• How do I adjust the output voltage of the LM2574HVMX-ADJ/NOPB?
  The output voltage of the LM2574HVMX-ADJ/NOPB can be adjusted by connecting a resistive divider network between the output and the ADJ pin. The output voltage can be calculated using the formula: Vout = 1.23 x (1 + R1/R2), where R1 and R2 are the resistors in the divider network.
• What is the purpose of the EN pin on the LM2574HVMX-ADJ/NOPB?
  The EN (Enable) pin is used to enable or disable the regulator. When the EN pin is pulled low, the regulator is disabled and the output voltage is turned off. When the EN pin is pulled high, the regulator is enabled and the output voltage is turned on.
