In summary, a Distributed Power Architecture is ideal for powering today’s power hungry FPGAs. Intermediate bus converters can drive 5V or 12V POLs (Point of Load), deriving the power from a 24V or 48V input. The POLs can also be driven directly from a 12V or 5V source. Each architecture has its advantages and disadvantages for both pcb design and best efficiency. It is important to perform calculations and thermal measurement to avoid over stressing the converters. TDK-Lambda offers a range of high efficiency isolated bus and POL converters.
