LM2673SD-3.3/NOPB Frequently Asked Questions (FAQ)

  • The maximum input voltage that can be applied to the LM2673SD-3.3/NOPB is 15V, but it's recommended to keep it below 12V for optimal performance and reliability.

  • The LM2673SD-3.3/NOPB has a maximum operating junction temperature of 150°C, but it's recommended to keep it below 125°C for optimal performance and reliability. You may need to consider thermal management and derating for high-temperature applications.

  • To ensure the stability of the output voltage, make sure to use the recommended output capacitor value and type, and keep the output capacitor close to the device. Also, ensure that the input voltage is within the recommended range and the device is operated within its specified temperature range.

  • Yes, the LM2673SD-3.3/NOPB can be used in low-power applications, but it's essential to ensure that the device is operated within its specified minimum load current requirement (typically 10mA) to maintain output voltage regulation.

  • The power dissipation of the LM2673SD-3.3/NOPB can be calculated using the formula: Pd = (Vin - Vout) x Iout, where Vin is the input voltage, Vout is the output voltage, and Iout is the output current. You can also use the thermal resistance (RθJA) and maximum junction temperature to estimate the power dissipation.
