LTC3858EUH#TRPBF Frequently Asked Questions (FAQ)
-
The maximum input voltage that can be applied to the LTC3858EUH is 28V, but it's recommended to keep it below 24V for reliable operation.
-
To minimize EMI, it's recommended to keep the input and output capacitors close to the IC, use a solid ground plane, and keep the high-frequency switching nodes (e.g. SW node) away from sensitive analog nodes.
-
The recommended PCB footprint for the LTC3858EUH is a QFN 5x5mm package with a 0.5mm pitch. It's recommended to follow the land pattern and thermal pad recommendations in the datasheet.
-
To select the right inductor, consider the maximum current rating, inductance value, and DCR (DC resistance). A good starting point is to use an inductor with a current rating of at least 1.5x the maximum output current, and an inductance value between 1uH to 10uH.
-
The thermal derating for the LTC3858EUH is typically around 1.5°C/W for the junction-to-ambient thermal resistance. This means that for every 1W of power dissipation, the junction temperature will increase by 1.5°C.
