LM2594DADJR2G Frequently Asked Questions (FAQs)

  • The maximum input voltage is 40V, but it's recommended to keep it below 35V for reliable operation.
  • Use a high-quality output capacitor with low ESR, and ensure the feedback resistors are of high precision (1% or better). Also, keep the output capacitor close to the IC to minimize noise.
  • The minimum input voltage is 4V, but it's recommended to keep it above 5V for reliable operation.
  • The LM2594DADJR2G is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage at high temperatures to ensure reliable operation.
  • The output voltage is calculated using the formula: Vout = 1.23 * (R1 + R2) / R2, where R1 and R2 are the feedback resistors.
