LM3881MM/NOPB Frequently Asked Questions (FAQs)

  • TI recommends using a 10uF ceramic capacitor in parallel with a 100nF ceramic capacitor, placed as close as possible to the power pins (VIN and GND) to ensure stable operation.
  • To ensure the LM3881 operates within its SOA, ensure that the output current does not exceed 3.5A, the input voltage does not exceed 28V, and the junction temperature does not exceed 150°C.
  • The bootstrap capacitor (CB) is used to generate a voltage that is higher than the input voltage, allowing the LM3881 to drive the output stage. A 10uF to 22uF capacitor is recommended for CB.
  • To minimize EMI, use a ground plane, keep the layout compact, use shielded cables, and ensure that the power supply is well-filtered. Additionally, use a common-mode choke or ferrite bead on the output to reduce EMI radiation.
  • The recommended heatsink for the LM3881 depends on the specific application and power dissipation. However, a heatsink with a thermal resistance of 10°C/W or lower is recommended to ensure reliable operation.
