LTC3101 - IC 0.54 A DUAL SWITCHING CONTROLLER, 1520 kHz SWITCHING FREQ-MAX, PQCC24, 4 X 4 MM, 0.75 MM HEIGHT, LEAD FREE, PLASTIC, MO-220WGGD, QFN-24, Switching Regulator or Controller
The maximum input voltage that the LTC3101 can handle is 38V, but it's recommended to keep it below 36V for reliable operation.
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.
The RUN pin is an active-high enable input that allows the user to turn the converter on and off. To use it, simply tie the RUN pin to VIN if you want the converter to be always on, or connect it to a logic signal that controls the converter's operation.
To compensate the LTC3101 for stability, a Type II compensation network is recommended. The datasheet provides a detailed example of how to design the compensation network, including the values of the required components.
The minimum ESR required for the output capacitor is 10mΩ. However, it's recommended to use an output capacitor with an ESR of less than 5mΩ to ensure stable operation.
