Choosing the appropriate capacitor technology, storage inductors, switching frequency and semiconductors, among other factors, is vital for the efficiency of DC/DC switching regulators with relatively high input and output currents. A high-efficiency switching regulator is market-ready if it, and the product in which it is used, comply with all necessary EMC standards. This often means that further filters must be included at the input and output to reduce emissions of interference. With high input and output currents, it is difficult to find a compromise between the efficiency, size, damping and cost of the filter, and the actual performance level.
