LM2574M-3.3/NOPB Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LM2574M-3.3/NOPB is 40V. 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 10uF with an ESR of 1 ohm or less, and to place the output capacitor close to the output pin of the device.
  • The minimum input voltage required for the LM2574M-3.3/NOPB to operate is 7V. However, the device can operate with an input voltage as low as 4V, but with reduced performance.
  • The LM2574M-3.3/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 input voltage at high temperatures.
  • The output voltage ripple of the LM2574M-3.3/NOPB can be calculated using the formula: ΔVout = (Iout x Rl) / (f x C), where Iout is the output current, Rl is the load resistance, f is the switching frequency, and C is the output capacitance.
