LTC3639EMSE#PBF Frequently Asked Questions (FAQ)
-
The maximum input voltage that the LTC3639EMSE can handle is 40V, but it's recommended to keep it below 36V for reliable operation.
-
To optimize the inductor selection, consider the inductor's saturation current, DC resistance, and core material. A good starting point is to choose an inductor with a saturation current rating of at least 1.5 times the maximum output current, and a DC resistance of less than 100mΩ.
-
For optimal performance, keep the input and output capacitors close to the IC, and use a solid ground plane to reduce noise. Keep the high-current paths (VIN, VOUT, and GND) short and wide, and avoid routing sensitive signals near the inductor.
-
Ensure good airflow around the IC, and consider adding a heat sink if the device will be operating at high temperatures or high currents. Monitor the junction temperature (TJ) and ensure it stays below 125°C.
-
The EXTVCC pin is an external VCC input that allows the IC to be powered from an external voltage source, which can be useful in systems where the input voltage is not available or is too high for the internal regulator.
