LM2576HVT-ADJ/NOPB Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LM2576HVT-ADJ/NOPB is 60V. Exceeding this voltage can cause damage to the device.
  • To ensure the stability of the output voltage, it is recommended to use a minimum output capacitance of 22uF and a maximum ESR of 1 ohm. Additionally, the output voltage should be decoupled with a 10uF capacitor.
  • The minimum input voltage required for the LM2576HVT-ADJ/NOPB to operate is 7V. However, the device can operate down to 4V with reduced performance.
  • The LM2576HVT-ADJ/NOPB is rated for operation up to 125°C. However, the device's performance and reliability may degrade at high temperatures. It is recommended to derate the device's output current and voltage at high temperatures.
  • The output voltage of the LM2576HVT-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).
