DEMO MANUAL  
DC2155A-A/DC2155A-B  
LTC3886IUKG/LTC3870EUFD  
60V Dual Output Step-Down DC/DC Controller  
with Digital Power System Management  
DESCRIPTION  
Demonstration circuit 2155A is available in two configu-  
rations. The DC2155A-A is a dual output synchronous  
step-down converter featuring the LTC®3886IUKG, a  
dual-phase current mode controller. The DC2155A-B is  
a single output synchronous step-down converter that  
operates with four phases: two from the LTC3886IUKG  
and two from LTC3870EUFD, a phase extender. Both ver-  
sions have a PMBus interface and digital power system  
management functions.  
anyserialbuscommunication.Thisallowseasyevaluation  
of the DC/DC converter aspects of the LTC3886. To fully  
exploretheextensivepowersystemmanagementfeatures  
of the parts, download the GUI software LTpowerPlay®  
2
onto your PC and use LTC’s I C/SMBus/PMBus Dongle  
DC1613A to connect to the board. LTpowerPlay allows  
the user to reconfigure the part on the fly and store the  
configuration in EEPROM, view telemetry of voltage, cur-  
rent, temperature and fault status.  
The DC2155A uses discrete MOSFETs in the power stage.  
The input range of this board is from 18V to 54V. The  
outputvoltagecanbeprogrammedfrom5Vto12Vwithan  
output current of up to 12A per phase. For the DC2155A-A  
version, the factory default setting for the CH0 output is  
12V and CH1 output is 5V. In addition, this demo board  
hasanon-boarddynamicloadcircuit, whichmakesiteasy  
to evaluate the transient performances.
