This DC/DC Converter was originally developed for aerospace applications but has found use in many other projects because of its flexibility and simplicity.
The power supply is a cascaded system with an unregulated, isolated DC-DC converter followed by a set of regulated buck converters. There is also provision for using a linear regulator for low-noise applications.
The ability to generate positive and negative voltages is convenient for systems using analog circuits based on operational amplifiers and comparators. The two high-current regulators are useful for power such subsystems as RF power amplifiers, DSPs and FPGAs.
