LM22671MRX-5.0/NOPB datasheet by Texas Instruments

LM22671MRX-5.0/NOPB Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the LM22671MRX-5.0/NOPB can handle?
  The maximum input voltage is 42V, but it's recommended to keep it below 40V for reliable operation.
• How do I ensure the stability of the output voltage?
  To ensure stability, make sure to use the recommended output capacitor values and types, and keep the output voltage within the specified range (4.5V to 5.5V).
• What is the minimum input capacitance required for the LM22671MRX-5.0/NOPB?
  The minimum input capacitance required is 10uF, but it's recommended to use a 22uF or larger capacitor for optimal performance.
• Can I use the LM22671MRX-5.0/NOPB in a high-temperature environment?
  The LM22671MRX-5.0/NOPB is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage at higher temperatures to ensure reliable operation.
• How do I calculate the output voltage of the LM22671MRX-5.0/NOPB?
  The output voltage is set by the resistor divider network (R1 and R2) connected to the FB pin. Use the formula: Vout = 1.285 x (1 + R2/R1) to calculate the output voltage.
