  DESIGN FEATURES Hot Swap Controller Enforces
  Tracking in Split Supply Systems
  by Ted Henderson Introduction Split power supplies are widely used in
  audio, video and data communication
  systems. These systems typically use
  В±5V, В±12V or В±15V supply voltages
  and require a wide range of operating currents. The LT4220 Hot Swap
  controller—which operates over any
  combination of split supplies ranging from ±2.7V to ±16.5V—allows
  a circuit board to be safely inserted
  or removed from a live backplane
  without glitching the power supplies
  while controlling load currents from
  milliamps to amps.
  Glitches can cause anything from
  objectionable “pops” in audio systems,
  data loss in digital systems or even
  connector damage. Pops can also
  originate from shifting bias points or
  complementary stages wherein half of
  the circuit is correctly powered and the
  other half has not yet been powered.
  The LT4220 offers the usual Hot …
