LM3671MF-3.3 Frequently Asked Questions (FAQ)

  • The maximum input voltage that can be applied to the LM3671MF-3.3 is 15V, but it's recommended to keep it below 12V for optimal performance and reliability.

  • The LM3671MF-3.3 is rated for operation up to 125°C, but the junction temperature should be kept below 150°C to ensure reliability. It's recommended to use thermal management techniques, such as heat sinks or thermal pads, to keep the device within the recommended temperature range.

  • To ensure the stability of the output voltage, it's recommended to use a minimum output capacitance of 10uF, and to keep the output voltage ripple below 1% of the nominal output voltage. Additionally, the input voltage should be well-regulated and free of noise.

  • Yes, the LM3671MF-3.3 can be used in battery-powered devices. It has a low quiescent current of 20uA, which makes it suitable for battery-powered applications. However, it's recommended to use a low-dropout linear regulator or a switching regulator with a low quiescent current to minimize power consumption.

  • The output voltage ripple can be calculated using the following formula: ΔVout = (Iout * ESL) / (Cout * fsw), where ΔVout is the output voltage ripple, Iout is the output current, ESL is the equivalent series inductance of the output capacitor, Cout is the output capacitance, and fsw is the switching frequency.
