LM3404HVMA/NOPB datasheet by Texas Instruments

LM3404HVMA/NOPB Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the LM3404HVMA/NOPB can handle?
  The LM3404HVMA/NOPB can handle input voltages up to 40V, but it's recommended to keep the input voltage below 36V for optimal performance and reliability.
• How do I ensure the stability of the output voltage?
  To ensure stability, make sure to use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Also, ensure that the input voltage is within the recommended range and the output current is within the specified limits.
• What is the maximum output current that the LM3404HVMA/NOPB can provide?
  The LM3404HVMA/NOPB can provide a maximum output current of 3A, but it's recommended to keep the output current below 2.5A for optimal performance and reliability.
• How do I choose the right inductor value for my application?
  The inductor value depends on the input voltage, output voltage, and output current. A good starting point is to use the inductor value recommended in the datasheet (22uH). You can also use the inductor selection guide provided by Texas Instruments to find the optimal inductor value for your application.
• What is the thermal shutdown temperature of the LM3404HVMA/NOPB?
  The thermal shutdown temperature of the LM3404HVMA/NOPB is 150°C. The device will shut down when the junction temperature exceeds this value, and will restart when the temperature drops below 140°C.
