ATC210

ATC210 Dual Series | 210 W DC-DC Intermediate Bus Converters ATC210 Dual-Input Bus Converter Integrated Power Conversion and Power Management Solution Footprint optimized for high-density ATCA applications Accepts inputs from both -48 V “A” and “B” feeds Power management functions include ORing, inrush control and transient protection 210 W on 12 V Intermediate Bus 6 W on 3.3 V Management Power Bus I2C serial bus interface for monitoring and reporting Programmable alarm thresholds via I2C Bus Hardware alarms via opto-isolators for loss of A or B feeds Comprehensive protection circuitry - current, voltage and temperature RoHS compliant The dual input ATC210 bus converter provides AdvancedTCA (ATCA/PICMG3.0) board designers a compact and rugged solution for generating intermediate bus voltages in a footprint-optimized package. The ATC210 is more than a power converter. It also provides power interface and power management functionality. The power interface functions include ORing, filtering and inrush control, while power management functionality is facilitated by both I2C serial bus and direct high-speed interfaces. Critical alarms, such as loss of A or B feeds, are hardware-implemented. Other alarms are implemented over an I2C serial bus which is enhanced with an interrupt pin. The solution is provided in a 2.3 x 1.8 inch (59mm x 46mm) footprint and provides an optimized solution for space-constrained systems that employ distributed power architectures.
