Hello, my name is Josh Broline, product marketing manager for Intersil space and high reliablilty products. Here at Apec 2012, I am demoing industry's only monolithic power solution for FPGA power.
See here, on this eval board, we have three space grade power solutions. The ISL70001, which is a 6 amp voltage regulator with integrated FETS. The ISL70002, a 12 amp solution, and the ISL75051, an ultra low LDO.
Now these are all specifically designed for space level environment. For more information on our fully monolithic power solution for FPGA, go to www.intersil.com/space.
There you can find Gerber files and schematics for this reference design.
