LM5156HQPWPRQ1 Frequently Asked Questions (FAQs)

  • A 2-layer or 4-layer PCB with a solid ground plane and thermal vias is recommended. Place the device near a thermal pad or a heat sink to improve heat dissipation.
  • Use a heat sink or thermal pad, and ensure good airflow around the device. Also, consider derating the output current and voltage according to the temperature derating curve in the datasheet.
  • Use low-ESR capacitors with a voltage rating of at least 2x the input voltage. For the input capacitor, a 10uF to 22uF ceramic or film capacitor is recommended. For the output capacitor, a 10uF to 47uF ceramic or film capacitor is recommended.
  • Use a shielded inductor, keep the input and output traces short and away from sensitive circuits, and add a common-mode choke or EMI filter if necessary. Also, ensure good grounding and decoupling of the device.
  • Apply the input voltage first, then the enable signal. Ensure the input voltage is stable before applying the enable signal. Also, ensure the output capacitor is fully charged before applying the load.
