Considering AdvancedTCA power subsystems

摘要

The AdvancedTCA specification calls out a well-defined set of power management requirements to provide specific interfaces to the shelf manager, which controls the on/off status and monitors each ATCA board's power subsystem. Each board requires a redundant -48-V feed with EMI filtering, safety isolation, inrush limiting, and enough holdup to ride through a 5-ms short on both inputs.
