LMR51430XFDDCR 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 dissipate heat efficiently. A minimum of 2 oz copper thickness is recommended for the top and bottom layers.
  • Ensure the input voltage is within the recommended range of 3.5V to 36V, and the output voltage is set within the specified range. Also, ensure the device is operated within the recommended temperature range of -40°C to 150°C.
  • A 10uF to 22uF ceramic capacitor with an X7R or X5R dielectric is recommended for input decoupling. The capacitor should be placed as close as possible to the VIN pin.
  • The output voltage ripple can be calculated using the formula: ΔVout = (Iout * ESL) / (Cout * fsw), where ESL is the equivalent series inductance of the output capacitor, Cout is the output capacitance, and fsw is the switching frequency.
  • A 22uF to 47uF ceramic capacitor with an X7R or X5R dielectric is recommended for output filtering. The capacitor should be placed as close as possible to the VOUT pin.
