LMR14030SQDDAQ1 Frequently Asked Questions (FAQ)

  • Texas Instruments recommends a 2-layer or 4-layer PCB with a solid ground plane and thermal vias to the bottom layer to dissipate heat efficiently.

  • Monitor the input voltage, output voltage, and output current to ensure they are within the recommended operating conditions specified in the datasheet.

  • A ceramic capacitor with a value of 10uF to 22uF is recommended for input decoupling, placed as close to the device as possible.

  • Use a shielded enclosure, keep the device away from noise sources, and use a common-mode choke or ferrite bead on the input lines to minimize EMI.

  • A ceramic capacitor with a value of 10uF to 22uF is recommended for output filtering, placed as close to the device as possible.
