LM5156DSSR Frequently Asked Questions (FAQs)

  • The LM5156DSSR can handle input voltages up to 60V, but it's recommended to operate within the specified input voltage range of 4.5V to 42V for optimal performance and reliability.
  • To ensure the LM5156DSSR 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 maximum junction temperature (TJ) is 150°C.
  • For optimal performance, it's recommended to follow a 4-layer PCB stack-up with a solid ground plane, keep the input and output capacitors close to the device, and use short, wide traces for the power paths. Avoid routing sensitive signals near the inductor.
  • Choose an inductor with a high saturation current rating, low DC resistance, and a suitable inductance value (e.g., 1-10 μH). The inductor should also be able to handle the peak current and have a high self-resonant frequency.
  • The EN (enable) pin is used to turn the device on or off. When EN is high, the device is enabled, and when EN is low, the device is disabled and enters a low-power shutdown mode.
