LM2679SX-12/NOPB Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LM2679SX-12/NOPB is 15V. Exceeding this voltage may damage the device.
  • To ensure the stability of the output voltage, it is recommended to use a minimum output capacitance of 22uF with an ESR of 0.05 ohms or less, and to place the output capacitor close to the output pin of the device.
  • The maximum output current that the LM2679SX-12/NOPB can deliver is 3A. Exceeding this current may cause the device to overheat or shut down.
  • The output voltage ripple of the LM2679SX-12/NOPB can be calculated using the formula: ΔVout = (Iout x Rl) / (f x Cout), where Iout is the output current, Rl is the load resistance, f is the switching frequency, and Cout is the output capacitance.
  • The thermal shutdown temperature of the LM2679SX-12/NOPB is 150°C. If the junction temperature exceeds this value, the device will shut down to prevent damage.
