LM3489MMX Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LM3489MMX is 42V, but it's recommended to keep it below 40V for reliable operation.
  • To ensure the LM3489MMX operates within its thermal limits, make sure to provide adequate heat sinking, keep the ambient temperature below 85°C, and avoid high power dissipation.
  • Yes, the LM3489MMX is qualified for automotive and high-reliability applications, but you should consult the Texas Instruments Automotive or High-Reliability documentation for specific requirements and guidelines.
  • To minimize EMI, keep the LM3489MMX away from noise sources, use a solid ground plane, and ensure that the input and output traces are separated and shielded.
  • The recommended input capacitor value is 10uF to 22uF, and it should be a low-ESR ceramic or film capacitor with a voltage rating of at least 50V.
