LM2670SX-3.3/NOPB Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LM2670SX-3.3/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 capacitor as close to the output pin as possible.
  • The maximum output current that the LM2670SX-3.3/NOPB can provide is 3A. Exceeding this current may cause the device to overheat or shut down.
  • The output voltage ripple can be calculated using the formula: ΔVout = (Iout x ESR) / (f x C), where Iout is the output current, ESR is the equivalent series resistance of the output capacitor, f is the switching frequency, and C is the output capacitance.
  • The feedback pin (FB) is used to sense the output voltage and regulate it to the desired value. It is connected to the output voltage through a resistive divider network to provide feedback to the internal error amplifier.
