LM5155DSST Frequently Asked Questions (FAQs)

  • The LM5155DSST can handle input voltages up to 60V, but it's recommended to keep it below 40V for optimal performance and reliability.
  • To ensure the LM5155DSST operates within its thermal limits, make sure to provide adequate heat sinking, keep the device away from heat sources, and avoid high ambient temperatures. The thermal resistance of the package is 25°C/W, so ensure the PCB design takes this into account.
  • For optimal performance, place the LM5155DSST close to the input capacitors and keep the high-current paths short. Ensure the PCB layout is symmetrical and balanced to minimize electromagnetic interference (EMI).
  • Choose input capacitors with a voltage rating of at least 2x the maximum input voltage, and a capacitance value that meets the recommended minimum of 10uF. X5R or X7R ceramic capacitors are recommended for their low ESR and high reliability.
  • The recommended output capacitor value is 10uF to 22uF, with a voltage rating of at least 2x the output voltage. Use a low-ESR capacitor such as an X5R or X7R ceramic capacitor to minimize output voltage ripple.
