LMR62421XMFX/NOPB Frequently Asked Questions (FAQs)

  • A 2-layer or 4-layer PCB with a solid ground plane and thermal vias is recommended. The device should be placed near a thermal pad or a heat sink to dissipate heat efficiently.
  • To ensure stability, use a minimum output capacitance of 10uF, and ensure the output voltage is within the recommended range. Also, use a low-ESR capacitor and a 1uF ceramic capacitor in parallel to filter out high-frequency noise.
  • The maximum input voltage is 26V, but it's recommended to operate within the recommended input voltage range of 3.5V to 20V for optimal performance and reliability.
  • Use an external current sense resistor and a fuse to limit the input current. Also, implement thermal monitoring and shutdown circuitry to prevent overheating. The device also has built-in overcurrent and thermal protection, but external protection is recommended for added safety.
  • Yes, the device is qualified for automotive and high-reliability applications. It meets the AEC-Q100 standard and has been tested for robustness and reliability in harsh environments.
