LTC3859IUHF#TRPBF Frequently Asked Questions (FAQ)
-
The maximum input voltage that can be applied to the LTC3859IUHF is 60V, but it's recommended to keep it below 55V 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 away from sensitive analog nodes. Also, use a shielded inductor and orient it to minimize radiation.
-
The recommended PCB footprint for the LTC3859IUHF is a 4-layer board with a solid ground plane, and the IC should be placed on the top layer. The input and output capacitors should be placed close to the IC, and the inductor should be placed on the bottom layer.
-
To select the right inductor for the LTC3859IUHF, consider the inductor's saturation current, DC resistance, and core material. A shielded inductor with a low DC resistance and high saturation current is recommended. The inductor value should be chosen based on the output voltage and current requirements.
-
The thermal derating for the LTC3859IUHF is 1.5°C/W above 25°C. This means that for every 1°C increase in ambient temperature above 25°C, the maximum power dissipation should be derated by 1.5W.
