LM5175PWPT 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 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 output capacitor, inductor, and load characteristics.
  • The maximum allowed input voltage for the LM5175PWPT is 42V, but it's recommended to keep the input voltage below 38V to ensure reliable operation and minimize the risk of damage.
  • The LM5175PWPT is rated for operation up to 125°C, but the maximum junction temperature (TJ) should not exceed 150°C. Ensure proper thermal design and heat sinking to maintain a safe operating temperature.
  • Connect the external clock signal to the SYNC pin, and ensure the clock frequency is within the recommended range of 200 kHz to 1 MHz. The LM5175PWPT will synchronize its switching frequency to the external clock signal.
