One of the parameters of an isolated DC-DC converter is the range of the input voltage over which the converter can operate. For the industry-standard “bricks” available for the nominal 48V input telecom marketplace, this range is usually 36V to 75V, or a ratio of about 2:1 from the highest to the lowest value. But there are many applications where a converter that can handle a much wider range of input voltage variation is desirable. For instance, in some systems the distributed input voltage has significant transients and surges that last too long to be removed by a filter.
