LM3671LC-1.6/NOPB datasheet by Texas Instruments

LM3671LC-1.6/NOPB Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LM3671LC-1.6/NOPB?
  The maximum input voltage that can be applied to the LM3671LC-1.6/NOPB is 15V, but it's recommended to keep it below 12V for optimal performance and reliability.
• Can I use the LM3671LC-1.6/NOPB in a high-temperature environment?
  The LM3671LC-1.6/NOPB is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage at high temperatures to ensure reliability and prevent thermal shutdown.
• How do I ensure the stability of the output voltage in my design?
  To ensure output voltage stability, make sure to follow the recommended layout and component selection guidelines in the datasheet, including the use of a 10uF ceramic capacitor at the output and a 1uF ceramic capacitor at the input.
• Can I use the LM3671LC-1.6/NOPB in a battery-powered device?
  Yes, the LM3671LC-1.6/NOPB is suitable for battery-powered devices due to its low quiescent current (IQ) of 20uA, which helps to extend battery life.
• How do I calculate the output voltage ripple of the LM3671LC-1.6/NOPB?
  The output voltage ripple can be calculated using the formula: ΔVout = (Iout * ESL) / (Cout * fsw), where ESL is the equivalent series inductance of the output capacitor, Cout is the output capacitance, and fsw is the switching frequency.
