LM2594HVMX-3.3/NOPB datasheet by Texas Instruments

LM2594HVMX-3.3/NOPB Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LM2594HVMX-3.3/NOPB?
  The maximum input voltage is 42V, but it's recommended to keep it below 40V for reliable operation.
• How do I ensure the output voltage is stable and accurate?
  Use a high-quality output capacitor with low ESR, and ensure the input voltage is stable and within the recommended range. Also, follow the recommended PCB layout guidelines to minimize noise and oscillations.
• What is the minimum input voltage required for the LM2594HVMX-3.3/NOPB to operate?
  The minimum input voltage is 4.5V, but it's recommended to keep it above 5V for reliable operation.
• Can I use the LM2594HVMX-3.3/NOPB in a high-temperature environment?
  The LM2594HVMX-3.3/NOPB 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.
• How do I calculate the output voltage tolerance of the LM2594HVMX-3.3/NOPB?
  The output voltage tolerance is typically ±2% of the nominal output voltage (3.3V). This means the output voltage can vary between 3.234V and 3.366V.
