LTC3421EUF#TRPBF Frequently Asked Questions (FAQ)
-
The maximum input voltage that the LTC3421 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 above the peak current of the converter, and a DC resistance that minimizes losses.
-
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 switching node (SW pin) away from sensitive analog nodes, and use a Kelvin connection for the output voltage sense lines.
-
To compensate the LTC3421, use a Type II compensation network consisting of a series RC network (R1, C1) and a parallel RC network (R2, C2) connected to the COMP pin. The values of these components depend on the specific application and can be calculated using the datasheet's compensation calculator.
-
The maximum output current that the LTC3421 can deliver is 2A, but this depends on the input voltage, output voltage, and inductor selection. Be sure to check the datasheet's thermal and electrical specifications to ensure the device can handle the required output current.
