LM3450MT/NOPB Frequently Asked Questions (FAQs)

  • Texas Instruments recommends a 2-layer or 4-layer PCB with a solid ground plane on the bottom layer and a thermal relief pattern on the top layer to minimize thermal resistance. A thermal pad on the bottom of the IC should be connected to the ground plane.
  • To ensure reliable start-up and operation, it's recommended to add a soft-start circuit to limit the inrush current and a voltage supervisor to monitor the input voltage. Additionally, a bulk capacitor with a low ESR should be used to filter the input voltage.
  • The maximum junction temperature (Tj) for the LM3450MT/NOPB is 150°C. However, it's recommended to design for a maximum Tj of 125°C to ensure reliable operation and minimize thermal stress.
  • Yes, the LM3450MT/NOPB is qualified for automotive and high-reliability applications. However, it's essential to follow the recommended design and layout guidelines, and to perform thorough testing and validation to ensure the device meets the specific requirements of the application.
  • To minimize EMI, it's recommended to use a shielded inductor, keep the switching node (SW) as short as possible, and use a common-mode choke or EMI filter on the input and output lines. Additionally, a good PCB layout with a solid ground plane and minimal signal routing can help reduce EMI.
