  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,
  ≤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 densities—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 …
