LTC3440EMS#PBF Frequently Asked Questions (FAQ)
-
The maximum input voltage that the LTC3440EMS can handle is 18V, but it's recommended to keep it below 15V for optimal performance and reliability.
-
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 and EMI. Keep the high-current paths short and wide, and avoid routing sensitive signals near the inductor.
-
The output voltage of the LTC3440EMS can be adjusted by changing the resistor divider ratio between the FB pin and the output voltage. Use the formula Vout = 0.8V x (R1 + R2) / R2 to calculate the desired resistor values.
-
The LTC3440EMS has a thermal derating of 2.5mW/°C above 25°C. This means that the maximum power dissipation decreases by 2.5mW for every degree Celsius above 25°C.
