As new generations of space grade FPGAs, DSPs, ASICs, memory, and other digital devices enter the market to meet the growing demand for increased bandwidth and data processing speed of the data processors and signal processors on-board a spacecraft, these new digital devices place unprecedented constraints on power supplies. For the large data and signal processor designs where the needs for power and/or current become a critical factor(s), the distributed power architecture (DPA) is often the power system of choice to ensure the optimum system performance. This paper presents the key design features and performances of a new point of load (POL) voltage regulator; one of the key elements of the DPA power system.

I may like to comment following: Can dc/dc converters and point of load manufacturer likes VPT, Vicor, IR, Crane and others derive some basic standard for their products so that user can replace one product with other? Does this product follow POLA or other standard? What about the EMI/EMC aspect? If we need to use it in military hardware, we need product with EMI/EMC compliance. Can you include more digital technology built into this product so that they have communication capability with micro controller and can easily be sequenced during power up and controlled and monitored in normal operation?

This paper is well-written, and describes new devices that are suitable for space use. This is a market of somewhat more limited scope than commercial power supply components, but is a good read just the same for people who have no need to design for aerospace systems. The concepts of distributed regulation are certainly applicable to commercial technology, so you can't go wrong by perusing this white paper even if your designs wind up in labs or locomotives.
