LT8641EUDC#TRPBF Frequently Asked Questions (FAQ)
-
The maximum input voltage that the LT8641EUDC can handle is 42V, but it's recommended to keep it below 36V for optimal performance and reliability.
-
To minimize EMI, keep the input and output capacitors close to the IC, use a solid ground plane, and keep the high-current paths short and direct. Also, use a shielded inductor and orient it to minimize radiation.
-
The recommended PCB footprint for the LT8641EUDC is a 4-layer board with a solid ground plane, and a thermal pad connected to the ground plane. The IC should be placed near the input capacitors and the output capacitors should be placed near the output pins.
-
Select an inductor with a high saturation current rating, low DC resistance, and a high self-resonant frequency. The inductor value should be between 1.5uH to 3.3uH, and the inductor should be shielded to minimize EMI.
-
The maximum output current that the LT8641EUDC can deliver is 2A, but it's recommended to keep it below 1.5A for optimal performance and reliability.
