LTC3544EUD#PBF Frequently Asked Questions (FAQ)

  • A good PCB layout for the LTC3544EUD involves keeping the input and output capacitors close to the IC, using a solid ground plane, and minimizing the length of the traces between the IC and the capacitors. A 4-layer PCB with a dedicated power plane and a solid ground plane is recommended.

  • To optimize the inductor selection, consider the inductor's saturation current, DC resistance, and core material. Choose an inductor with a saturation current rating above the peak current of the converter, and a DC resistance that minimizes losses. Ferrite or iron powder cores are suitable for the LTC3544EUD.

  • The maximum ambient temperature for the LTC3544EUD is 85°C. However, the junction temperature (TJ) should not exceed 125°C. Ensure proper thermal design and heat sinking to maintain a safe operating temperature.

  • Yes, the LTC3544EUD can be used in a synchronous buck configuration. This can improve efficiency by reducing the power losses in the external Schottky diode. However, ensure that the external FET is properly selected and driven to avoid shoot-through currents.

  • To troubleshoot the LTC3544EUD, start by verifying the input voltage, output voltage, and feedback voltage. Check for proper component selection, PCB layout, and soldering. Use an oscilloscope to inspect the waveforms and identify any anomalies. Consult the datasheet and application notes for guidance.
