LTC3873ITS8-5#TRPBF Frequently Asked Questions (FAQ)
-
A good PCB layout for the LTC3873 involves keeping the high-frequency switching nodes (e.g., SW, VIN, and VOUT) away from sensitive analog nodes, using a solid ground plane, and minimizing trace lengths and widths to reduce parasitic inductance and capacitance. A 4-layer board with a dedicated power plane and a solid ground plane is recommended.
-
When selecting an inductor for the LTC3873, 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, a DC resistance of less than 100mΩ, and a core material with low core loss (e.g., ferrite or powdered iron).
-
The maximum ambient temperature for the LTC3873 is 85°C, but the device can operate up to 125°C with derating. It's essential to consider the thermal design and heat sinking to ensure the device operates within its specified temperature range.
-
Yes, the LTC3873 is qualified for automotive and high-reliability applications. It meets the AEC-Q100 standard for automotive applications and is manufactured with a high-reliability process. However, it's essential to review the device's qualification data and perform additional testing to ensure it meets the specific requirements of your application.
-
To troubleshoot issues with the LTC3873, start by reviewing the PCB layout and ensuring it meets the recommended layout guidelines. Check the input and output voltage waveforms using an oscilloscope to identify any signs of oscillation or instability. Verify that the component values and types meet the recommended specifications, and check for any signs of overheating or thermal issues.
