DESIGN FEATURESвЂ‰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 …
