LM22676MRE-5.0/NOPB datasheet by Texas Instruments

LM22676MRE-5.0/NOPB Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LM22676MRE-5.0/NOPB?
  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 LM22676MRE-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 LM22676MRE-5.0/NOPB in a high-temperature environment?
  The LM22676MRE-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 ripple of the LM22676MRE-5.0/NOPB?
  The output voltage ripple can be calculated using the formula: ΔVout = (Iout * Rl) / (fsw * Cout), where Iout is the output current, Rl is the load resistance, fsw is the switching frequency, and Cout is the output capacitance.
