DESCRIPTION
LTC7131-1
25A Monolithic Synchronous DC/DC Step-
Down Converter with PMBus Interface
Demonstration circuit 2824A-A is a single output buck
converter with 4.5V to 20V input voltage range featuring
the
, a 25A monolithic synchronous step-
down converter with a PMBus interface. The output volt-
age is adjustable from 0.4V to 4V and the converter can
supply up to 25A of load current.
The DC2824A-A powers up to default settings and pro-
duces power based on configuration resistors without the
need for any serial bus communication, which allows easy
evaluation of the DC/DC converter.
To fully explore the extensive power system manage-
ment features of the part, download the GUI software
onto your PC and use ADI’s USB-to-PMBus
to connect to the board.

LTpowerPlay allows users to monitor fault status and
real-time telemetry of input and output voltages, input
and output current, and internal IC die temperature.
Programmable parameters include device address, out-
put voltage, on/off control, and fault response to output
overvoltage and output overcurrent.
The LTC7131-1 data sheet gives a complete description
of this part, its operation and application information and
must be read in conjunction with this quick start guide
for DC2824A-A.
