LM2594MX-5.0/NOPB Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LM2594 is 40V, but it's recommended to keep it below 35V for reliable operation.
  • To ensure a stable output voltage, make sure to use the recommended output capacitor (Cout) value and type, and keep the input voltage within the recommended range. Also, ensure the PCB layout is well-designed to minimize noise and EMI.
  • The minimum input voltage required for the LM2594 to operate is 7V, but it's recommended to keep it above 8V for reliable startup and operation.
  • The LM2594 is rated for operation up to 125°C, but it's recommended to keep the junction temperature below 115°C for reliable operation. Ensure proper thermal design and heat sinking to prevent overheating.
  • The output voltage of the LM2594 is determined by the resistor divider network (R1 and R2) connected to the feedback pin. Use the formula: Vout = 1.23 x (1 + R2/R1) to calculate the output voltage.
