Board mount power supplies are devices used to convert electrical power from some source into a format suitable for powering some desired load, such as DC to DC Converters. These power supplies are designed to be physically and mechanically connected within an application by means of attachment to a printed circuit board. Further distinctions within the category are made according to the general nature of the transformation performed.
