LM2674M-3.3 Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LM2674M-3.3 is 15V, but it's recommended to keep it below 12V for reliable operation.
  • The LM2674M-3.3 is rated for operation up to 125°C, but the output voltage may decrease at high temperatures. Ensure proper thermal design and consider derating the output current.
  • The output voltage tolerance of the LM2674M-3.3 is ±2% over the entire operating temperature range. This means the output voltage can vary by ±66mV (2% of 3.3V) from the nominal value.
  • The minimum input capacitance required for the LM2674M-3.3 is 10uF, but it's recommended to use a 22uF or larger capacitor to ensure stable operation.
  • The LM2674M-3.3 is a switching regulator, and it may generate switching noise. However, the device has built-in noise reduction features, and proper PCB layout and filtering can minimize the noise. Consider adding additional filtering components if necessary.
