Keeps Cool in Tight Spaces
Eddie Beville Each generation of high end processors, FPGAs and ASICs
demands more power, but even as power supplies are expected to
carry significantly heavier loads, they are given less board space to
do so. It is now common for POL (point-of-load) supplies to produce
multiple voltage rails at tens of amps to over a hundred amps at low,
в‰¤1V, output voltages, and in less space than the generation before.
Supplies that must support high load currents and fit in
tight spaces are often judged primarily on their power
density, or watts/cm2. Indeed, many of the latest packaged power supplies and discrete solutions proclaim
impressively high power densitiesвЂ”power supply manufacturers seem to be able to squeeze more and more
power from smaller packages. Unfortunately, there is a
big problem lurking behind amazing increases in power …
