LM5175PWPR 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 pin) away from sensitive analog nodes, and use a Kelvin connection for the output voltage sense lines.
  • Use the TI WEBENCH Power Designer tool to generate a compensation network based on the specific application requirements. The tool provides a suggested compensation network based on the output capacitor, inductor, and desired crossover frequency.
  • The maximum allowed input voltage ripple is 10% of the input voltage. Exceeding this limit may cause the device to malfunction or oscillate.
  • Yes, the LM5175PWPR can be used in a synchronous rectification configuration. However, this requires additional external components and careful PCB layout to ensure proper operation.
  • Use a thermal pad or a heat sink to dissipate heat from the device. Ensure good airflow around the device, and avoid blocking the thermal pad or heat sink with other components.
