  DESIGN FEATURES L Dual Hot Swap Controller Brings
  Digital Monitoring to AdvancedTCA,
  ВµTCA and AMC Applications
  by Josh Simonson Introduction
  Recently ratified plug-in card bus
  standards, such as AdvancedTCA,
  ВµTCA and AMC, reduce the number of
  power supplies that are routed across
  the connector when compared to earlier standards, such as CompactPCI.
  Bulk power is limited to one fairly high
  voltage supply, making for an efficient
  distribution channel. For instance,
  distributed 12V power is locally converted to lower voltages to minimize
  distribution currents and related
  losses in connectors and power handling circuitry. Some cards also have
  a lower voltage (3.3V) maintenance
  power supply that provides low current Even with the simplification
  that new plug-in standards
  bring, there remain rigorous
  power, heat dissipation and
  reliability requirements
  for Hot Swap, monitoring
  and control. The LTC4222 …
