LM4755TSX/NOPB Frequently Asked Questions (FAQs)

  • A 10uF capacitor in parallel with a 0.1uF capacitor, placed as close as possible to the power pins, is recommended for power supply decoupling.
  • To ensure stability, use a minimum of 100nF capacitor between the BYPASS pin and ground, and keep the PCB layout symmetrical and balanced to prevent oscillations.
  • The maximum power dissipation of the LM4755 is 15W, and it's essential to ensure proper heat sinking to prevent overheating.
  • Yes, the LM4755 can be used in a bridged configuration to increase the power output, but it requires a specific PCB layout and component selection to ensure stability and prevent oscillations.
  • Use a voltage regulator or a voltage supervisor to ensure the input voltage is within the recommended range of 9V to 26V, and consider adding over-voltage protection (OVP) and under-voltage protection (UVP) circuits to prevent damage.
