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.
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 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.
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.

During a short-circuit or when
current limit of 12 V is exceeded,
12 V latches off, 3.3 V remains
on. The 12 V can only be
enabled by cycling power, or
via the I2C interface, providing
the fault condition has cleared.
