LM2575-5.0WT - Microchip

LM2575-5.0WT Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LM2575-5.0WT?
  The maximum input voltage that can be applied to the LM2575-5.0WT is 40V, but it's recommended to keep it below 35V for reliable operation.
• How do I ensure the stability of the output voltage?
  To ensure the stability of the output voltage, make sure to use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Also, keep the output voltage sense lines short and away from noise sources.
• What is the minimum input voltage required for the LM2575-5.0WT to operate?
  The minimum input voltage required for the LM2575-5.0WT to operate is 7V, but it's recommended to keep it above 8V for reliable startup.
• Can I use the LM2575-5.0WT in a high-temperature environment?
  The LM2575-5.0WT 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 calculate the output voltage ripple of the LM2575-5.0WT?
  The output voltage ripple of the LM2575-5.0WT can be calculated using the formula: ΔVout = (Iout x ESR) / (f x C), where Iout is the output current, ESR is the equivalent series resistance of the output capacitor, f is the switching frequency, and C is the output capacitance.
