Integrated ATCA Power Entry Module and DC-DC Bus Converter

Emerson Network Power (Carlsbad, CA) has released an updated version of its integrated 250-W ATCA® power entry module and DC-DC bus converter. The ATCR250-48D12-03J integrates a 12-V primary intermediate bus output with a secondary 3.3-V management bus output, for ATCA control and monitoring functions. This simplifies the task of implementing dual redundant, hot swap -48VDC power distribution with EMI filtering on an ATCA or other telecom board.

While providing high-reliability, innovative features and compact design in a cost-effective package, the module significantly reduces the telecom board real estate. Power interface functions include ORing, filtering and inrush control, while power management functionality is facilitated by an I2C serial bus interface.
