LM2594N-5.0 datasheet by Texas Instruments

LM2594N-5.0 Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LM2594N-5.0?
  The maximum input voltage that can be applied to the LM2594N-5.0 is 40V, but it's recommended to keep it below 37V to ensure reliable operation and to prevent damage to the internal circuitry.
• Can I use the LM2594N-5.0 as a boost converter?
  No, the LM2594N-5.0 is a buck converter, which means it can only step down the input voltage to a lower output voltage. It cannot be used as a boost converter to step up the input voltage.
• How do I calculate the output voltage of the LM2594N-5.0?
  The output voltage of the LM2594N-5.0 is determined by the resistive divider network formed by R1 and R2. The formula to calculate the output voltage is: Vout = 5V * (1 + R2/R1).
• What is the minimum input voltage required for the LM2594N-5.0 to operate?
  The minimum input voltage required for the LM2594N-5.0 to operate is around 7V, but it's recommended to keep it above 8V to ensure reliable operation and to prevent dropout.
• Can I use the LM2594N-5.0 to generate a negative output voltage?
  No, the LM2594N-5.0 is designed to generate a positive output voltage only. If you need a negative output voltage, you'll need to use a different converter or add additional circuitry.
