LM25180QNGURQ1 Frequently Asked Questions (FAQs)

  • A good PCB layout for the LM25180QNGURQ1 should prioritize thermal dissipation. Place the device near a thermal pad or a heat sink, and ensure good copper pour coverage around the device. Avoid routing high-current traces under the device, and keep the thermal pad connected to a solid ground plane.
  • To ensure reliable start-up and shutdown, ensure that the input voltage rises and falls monotonically, and that the input voltage is above the UVLO threshold (around 2.5V) before enabling the device. Also, ensure that the output voltage is within the specified range during start-up and shutdown.
  • A low-ESR ceramic capacitor (e.g., X5R or X7R) with a value between 4.7uF to 10uF is recommended for the input capacitor. This helps to filter out high-frequency noise and ensure stable operation.
  • To minimize ripple and noise, use a combination of capacitors and inductors in the output filter. A good starting point is to use a 10uF ceramic capacitor and a 1uH inductor. Adjust the values based on the specific application requirements and desired ripple and noise performance.
  • Key considerations for thermal design and heat sinking include ensuring good thermal conductivity between the device and the heat sink, using a heat sink with a high thermal conductivity, and providing adequate airflow around the device. Aim for a thermal resistance (RθJA) of less than 10°C/W.
