LM5166XDRCR Frequently Asked Questions (FAQ)

  • The LM5166XDRCR can handle input voltages up to 65V, but it's recommended to keep it below 60V for reliable operation.

  • Make sure to provide adequate heat sinking, keep the device away from heat sources, and ensure good airflow around the device. Also, monitor the junction temperature (TJ) and adjust the operating conditions accordingly.

  • Use a 4-layer PCB with a solid ground plane, keep the input and output capacitors close to the device, and use short, wide traces for the high-current paths. Avoid routing high-current paths under the device.

  • Choose capacitors with low ESR, high ripple current rating, and a voltage rating that exceeds the maximum input voltage. For the output capacitor, select one with a capacitance value that meets the required output ripple and voltage rating.

  • The EN (enable) pin is used to turn the device on or off. When EN is high, the device is enabled, and when EN is low, the device is disabled and in a low-power state.
