  DESIGN FEATURES 48 Volt Hot Swap Controller
  for Negative Voltages by Henry Yun
  and Robert Reay Introduction
  As supply voltages for PC boards continue to drop, designers face the
  difficult task of minimizing the voltage drops through distributed power
  systems. At operating voltages of 3.3V
  or lower, the voltage drops across
  power busses, connector pins and
  inrush control circuitry can cause a
  supply voltage to drop out of tolerance. A solution to this problem is to
  distribute power at a high voltage,
  commonly 48V, and then step the
  voltage down to the final desired value
  on each board in the system, using
  power modules.
  Most 48V power modules require
  an input bypass capacitor with a typical value of hundreds of microfarads.
  When the board is hot-plugged into a
  live 48V power rail, the input capacitor can draw huge inrush currents as
  it charges. The inrush current can
  cause permanent damage to the
  board’s components and create
  glitches on the system power supply …
