LM5146RGYR Frequently Asked Questions (FAQs)

  • The LM5146RGYR can handle input voltages up to 60V, but it's recommended to keep it below 40V for optimal performance and reliability.
  • To ensure stability, make sure to use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Also, use a low-ESR capacitor for the output filter capacitor (Cout).
  • The LM5146RGYR can provide up to 2A of output current, but it's recommended to keep it below 1.5A for optimal performance and reliability.
  • The output voltage can be adjusted by using a resistive divider network between the output and the FB pin. The ratio of the resistors determines the output voltage.
  • The EN (enable) pin is used to enable or disable the regulator. When the EN pin is high, the regulator is enabled, and when it's low, the regulator is disabled.
