DESCRIPTION
LT8228 High Voltage, High Efficiency Bidirectional
Synchronous Buck or Boost Converter with Input and
Output Circuit Breakers
Demonstration circuit 2351A is a high voltage, high effi-
ciency synchronous buck or boost DC/DC converter. It is
designed to have 36V to 56V on one side and 8V to 14V
on the other side. It can supply a 35A maximum output
current in buck mode and delivers 7A of current in boost
mode. The demo board features the LT8228EFE control-
ler. This part can seamlessly transition from bucking to
boosting. With built-in circuit breaker function and other
protection features, the LT8228 is ideal for high reliability
systems requiring N+1 redundancy or other protections All registered trademarks and trademarks are the property of their respective owners.
PERFORMANCE SUMMARY
BOARD PHOTO
in industrial, automotive, medical, military, and avionics
applications.
The DC2351A is designed to be paralleled with other
DC2351A boards to increase the total output current.
With adequate heatsinking or airflow, the output current
can be increased.
Design files for this circuit board are available.
Specifications are at TA = 25°C

QUICK START PROCEDURE
It is highly recommended that the user first evaluates the
board in buck mode only, then in boost mode only before
moving to bidirectional evaluation. In bidirectional opera-
tion, make sure that the any power supply connected to
V1 or V2 is reverse current protected or capable of sink-
ing current. A battery or bank of super caps may also
be required to compensate for a slow turn on time the
power supply may have. Further, for ease of evaluation,
it is recommended to start with a minimum load of 1A in
buck mode. Refer to the following procedure:
1. Tie DRxN pin to INTVCC. Header H1 pins 9 and 13.
2. With power off, connect the input power supply to V1
(48V) and GND (input return).
3. Connect the 8.0V to 14V output load between V2
andGND.
4. Connect the DVMs to the input and the output.
5. Turn on the V1 power supply and then check for the
proper V2 voltage. V2 should be between 8.0V to 14V,
depending on the type of load.
6. Once the proper output voltages are established, adjust
the loads within the operating range and observe
the output voltage regulation, ripple voltage and
otherparameters.
7. Once you have completed evaluating buck mode of
operation, reverse the connections by connecting a
source to V2 (12V) and a load to V1. Tie DRxN pin to
GND. Header pins 9 and 14.
8. Once satisfied, the user can now evaluate in bidirec-
tional mode of operation by either directly driving the
DRxN pin or floating DRxN and letting the LT8228 self-
determine the operating mode.
