LM5170PHPT Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the switching node (SW) away from sensitive analog nodes, and use a shielded inductor to reduce EMI.
  • Use the TI's WEBENCH Power Designer tool to generate a compensation network based on the specific application requirements. The tool provides a recommended compensation network based on the device's operating conditions.
  • The maximum allowed input voltage for the LM5170PHPT is 60V, but it's recommended to operate within the specified input voltage range of 12V to 42V for optimal performance and reliability.
  • Use a thermal pad or a heat sink to dissipate heat, and ensure good airflow around the device. Monitor the device's temperature using the thermal monitoring pin (TMP) and adjust the operating conditions accordingly.
  • A low-ESR ceramic or polymer capacitor with a value between 10uF to 22uF is recommended. The output capacitor should be placed close to the output pins to minimize parasitic inductance.
