LMR14050SSQDDARQ1 Frequently Asked Questions (FAQs)

  • Texas Instruments recommends a 2-layer or 4-layer PCB with a solid ground plane and thermal vias to the bottom layer to optimize thermal performance. A minimum of 2 oz copper thickness is recommended.
  • Ensure the input voltage is within the recommended range of 4.5V to 18V, and the output voltage is within the specified range for the desired output voltage. Also, ensure the device is operated within the recommended junction temperature range of -40°C to 150°C.
  • A low-ESR ceramic capacitor with a value of 10uF to 22uF is recommended for the input capacitor. X5R or X7R dielectric types are suitable for this application.
  • Use a shielded inductor, keep the switching node (SW) away from sensitive nodes, and use a common-mode choke to reduce EMI. Additionally, ensure the PCB layout is optimized for minimal loop area and use a Faraday shield if necessary.
  • A low-ESR ceramic capacitor with a value of 10uF to 22uF is recommended for the output capacitor. X5R or X7R dielectric types are suitable for this application.
