LM2676S-3.3/NOPB Frequently Asked Questions (FAQs)

  • The maximum input voltage is 15V, but it's recommended to keep it below 12V for optimal performance and reliability.
  • To ensure stability, use a minimum output capacitance of 22uF, and an ESR (Equivalent Series Resistance) of 0.05 ohms or less. Also, place the output capacitor close to the regulator.
  • A minimum input capacitance of 10uF is recommended, but it's recommended to use a larger capacitor (e.g., 22uF) for better performance.
  • The LM2676S-3.3/NOPB is rated for operation up to 125°C, but the junction temperature should be kept below 150°C for reliability. Use a heat sink or thermal pad to ensure proper heat dissipation.
  • Power dissipation (PD) can be calculated using the formula: PD = (VIN - VOUT) x IOUT. Ensure the calculated PD is within the device's power rating (2.5W for the LM2676S-3.3/NOPB).
